Hey guys

. I am racking my brain and just about everyone else's brains on my starting problem other my redtop SR. U have all my spec in the previous email below this one. Well I go to start the car fuel pumps prime and I know I am getting fuel to the rail. Because I had to make my own rail brackets and getting them to seal was a pain.

Well when I parked the car everything was working fine. Spark was set perfectly. Cams are timed perfectly. Cas is set correctly. Well when I went to start it. It cranked and crank and cranked just wouldn't fire. I rechecked everything.**Connections. Grounds. Spark. Pulled the cas listened to injectors click correctly. Even put some oil in the sparkplug holes as the motor had sat drive for a year and still nothing.

Well I ran starting fluid into a vacuum line and cranked. U could smell it coming out the exhaust. Not burning at all. I unplug the ignitor and crank it a little then plug it back in. And boom she fires up I sit there with it Rev ed up for a bit and slowly ease off. And its idling right at 900 and wide band is reading 11.3. Its idling and reving perfect. We let it sit like this for a while. Then I go to unplug the tps to set the fuel pressure up. Because it was running about 33-35 Psi. As soon as I unplug the tps it dies. I come back later after the shop airs out. And She fires right up again. But this time it sounds like its running on three cylinders. Runs for a bit. So I turn it off to come back to it. And now it wont start again. I clean plugs. Even switch them out. Unplug and plug back in the ignitor nothing. I did notice that one coil was sparking weaker. And the spark doesn't seem as violent as normal. But its sparking on all four. I noticed on coil pack sparking out the side of the coil the one with weak spark. But the thing is its getting spark. Fuel and air in the right order.
And every eclectic thing was working peflrfect when parked.

The only stuff I changed was turbo bolt on stuff. And wiring in injector resistors and msd injector clips.



gt3076 ar size well i went with a .82 twinscroll figure it should be about perfect for my setup, being a sr20 that is 2.2 liters
96lb msd injectors. and dual walboro fuel pumps. should should flow plenty of fuel for race gas and street fuel


Code 55 on ecu
Dual tune Enthalpy

try shooting starter fluid in there again to see if it will start, whats fuel pressure at when you turn the key on?

What fuel filter do you have? Or you can spray son Starting fluid into the TB

33 psi is what it comes up to. Should be a few more psi. But when I pull the plugs out there is fuel on them. I hook a short vacuum line on the intake manifold bov bung. And spray fuild in that. And it pumps the starting fluid all the way through. Cause u can smell it strong in the exhaust

Z32 fuel filter. Its new. And the fuel lines in the engine bay are new. Its getting fuel. Spark and air. Started up and ran perfect. Now wont start again

Do you have a spare ignitor?

idahotuner

No I don't. I had one of my buddies sugest that also. He said he was Going to check for to see if he had an extra

Did you take the injectors out at anypoint before you were having problems? Is it possible you have torn the injector o-rings?

If you have any junkyards around you go load up on ignitors from j30s and z32s, I had a problem like this and I wired in a j30 and it was good from there. Now I have a few for this reason.

idahotuner

I have top feed msd injectors. So if the o ring leaks it runs down the outside. Yeah I would prefer to be able to just plug in a different one to see if it makes a difference

Also. If it was flooding out I would have figured it out. Because I have a fuel pump kill switch And I crank the engine over with the fuel pumps off. My old set up had leaking o rings and when I would kill the fuel and crank it. The extra fuel would burn up and start. This isn't acting like to much fuel or to little fuel.

Well two votes for ignitor

Any one thing the fuel is to old. Its was put in a year ago October.

No the age of the fuel wouldn't matter... Lol

A year is a while, you could always get it out and put some fresh gas in. I'm not sure on gas shelf life, but a year seems a long time lol.

89JDM240sx

When I sat put my 240 up it was sitting for a bout a yr and 4 months swapped in built KA and used the same gas no problems... But everybody does it diff

I know. I have had it sit for this long before and have the fuel be fine still.

Well I got an ignitor on the way. See if it makes a difference

I wouldn't say your fuel was too old to burn, but I wouldn't boost on it. Have you physically checked for spark? Have you tried unplugging the MAF and starting it? Is the engine timed right?

Yep physicaly watched spark. Cam to crank timing set perfectly. Spark timing is also. And injectors are shooting fuel.

I talked to Martin from Enthalpy and he said gas this old always has a hard time cold starting. But it seemed like if I turn off the fuel pump Ans spray starter fluid through it. That should get enough for it to fire up for a few seconds

when you get it running swap around the coilpacks to see if the miss in the cylinder travels to different cylinders...could be a bad coilpack

but it sounds like a bad ignitor for the not starting issue

idahotuner

Well I pumped all the. Old fuel out. Poured a little on the ground and tried lighting it with a match. And barely ignited. So fuel is a big part.

Yeah I know one coilpack is week. I am going get spit fires. But I need it running before I dump any money into it

Good luck bro

well it was bad gas
she is kicking over an firing up now. just got to do some timing adjustments to get her in the correct place and she should be purring like a kitten. fingers crossed

Allrighty you were right about the gas. I pumped it all out and put fresh fuel in and it ran. But I had messed around with my Cas timing that it was confused. So we reset my cas and it cranked and was catching like it would almost start up but then wouldn't. So then we had the Cas rotated all the way towards the back of the car and it started and wouldn't Rev over 500 rpm. So we figured it need to move that way a little more. Pull the Cause back out and set it correctly but at a way that gives me more rotation to the back. Well it starts up and is reving up to almost 2500ish and still not idling really. 400-500 rpm. We pulled the Cas again but accidentally put it in 360 degrees off so just cranked. Pulled the valve cover off so we could see the came and cas to know it was correct. And now its just cranking not coughing or anything. I have two ignitors that I switch back and forth but it has started on either. I also bridged the fuel pump relay but that didn't help any thing. Ecu is code 55, we have been using starting fluid. But we got one pretty badly back fire. So we kinda laid off that.

well i reset everything, cleaned the maf, was getting her to sputter again. but then it stopped firing but cranks hard. so i check the ecu codes 11 and 12 popped up. cas and maf

Well I figured got a new cas and check everything was set from cam timing to spark. Unplugged the maf and sprayed some starting fluid and she fired up with wot. Ran rough for about 30 secs. So I think that since the maf is bad its screwing timing up really bad enough to make it not start because of the large injectors and over bore and all. But unplug it throws it into limp mode and makes it run really rich that's why the throttle needed to be wide open to keep it running. What do you guys think

Bought a new Isis maf added some fuel from our tank. And she fired up.
