So I left my car to sit for 2 months during winter with a full tank of fuel with fuel stabilizer. Go to start it and it cranks , kinda want to ignite but it won't run. 1993 nissan 240sx ka24de.

Got a new fuel pump walbro.
Got sparks in all 4.
Self diagnosis reads code 55 " everything is good "
Battery is good, even try to boost with another car.
Took the old spark plugs out, they were wet , put in new spark plugs. Still doesn't go.

Anyone got any suggestions what it could be? There was 2 loose plugs that was on the harness that was running towards the injectors so I plugged them back in. Still not working. Unsure what it's for thou.

Thanks in advance.

Wet with what coolant, oil, or gas?

It was wet with fuel. Tried to start the car with a drain battery and the harness plug for the iacv was loose..

re-check those new plugs and make sure they aren't fouled. then check your grounds. Especially the one from the battery -> Tray -> Manifold.

You can eliminate MAF issue by unplugging it. I had an SR MAF go bad on me during a swap, ran fine before i pulled motor, and took a shit after i got it in the new car.

Double check your alternator wiring, make sure the connections are secure on the back.

I would pull your battery terminals and clean them up really good

Check fuel pressure
Check spark
Check compression

When you try to start it, what happens?

Hoonigan19

I actually noticed where the ground connects to the tray is rusted to shit! I'm gonna run a new ground from battery to a clean spot.

Thanks for the reply! Gonna try again after work

It fired a couple of rounds but didn't keep rolling. Then just died

Sounds like a grounding issue..... Check it and report back. Let's get this figured out.

PROBLEM SOLVED!

So the ground from the battery to the tray to the manifold. The contact point on the tray was rotten. So I got another ground cable going the the chassis.
The spark plug wires was also replaced because it was loose when I push them onto the spark plugs.
Also I properly disconnected all 4 injector plugs and try to fire the car at least like 7 times to burn up the fuel that was inside each cylinder. It was flooded for sure! It definitely runs on the flooded fuel for like 2 seconds and then gives out.
After that, there was still some slight bit of fuel inside the cylinder with the burnt oil crust. So I put some quick start into my air filter box, plugged all 4 injector back in. Fired her up with a full battery charge and IT RUNS!!

It was honestly a dumb mistake that I did when I try to start her up for the first time with a drain battery, loose IACV sub harness. That was probably what caused the cylinder to get flooded with fuel after a few tries.

Anyhow, Thanks everyone for the help, definitely a lot of help here. I can finally ditch my shitty civic lol !! Have a good one!

Can someone help me too!
My car started up fine then after 5 months on jackstands into changing the clutch and powersteering. Also for waiting on parts and stuff I needed. I tried to start the car, cranks but no fire up. Battery charged, ignition running, distributor is timed, sparks everything working. Looking into my ECU code says 55, at first I thought it was my ECU. Haven't look into it. But I thought I should try to figure out what could be else. Plus I live in Arizona so dry heat.
Also, i am planning to get an OBD cord an computer. Just ugh I miss driving it.

2... you will need to give us more info if youd like help...

What motor is in ur car?
The car cranks but no start.... is your fuel pump coming on? Do u have correct fuel pressure? Do u have injector pules? Are you getn spark at all 4 spark plugs?

Your car does not have OBD2; It's pre 1995. You'd need a Consult port if you want to communicate with the ECU. That isn't necessary though, you can do your own troubleshooting without it just fine.
