Rb won't fire up

[HungryHank]

fuel - yes
compression - yes
spark - no


rb20 doesnt have spark, I was driving it around my block and I pull over to talk with a friend then try to pull out. It bogged out on me and then died.

I tried to start it again, and it won't fire up. Car cranks like no tomorrow,but no dice.

first cylinder wont spark

Ive tried looking for blown fuses,grounds, relays
nothing.

any input?

Check EGI Relay, Make sure the ECU is sending signal to the Ignitier chip. check that each individual coil pack is getting a signal,

i remember wen i had this exact issue, i ended up finding out i somehow fried a section of my ecu, once i got a new one it fired rite up

[HungryHank]

i checked the relays

ecu lights work

Backtrack from the coil. Put a testlight on the signal wire into the back on the coil. If it doesn't flash when a buddy cranks, then follow back to the next component. I'm guessing since it doesn't even fire up that none of the coils fire. I'm not familiar with RBs, but do they have a single ignitor chip or power transistor like the sr or ka? If so, check the signal coming out of it. The KA's has 3 wires (i dont know how many the rbs have): 12v, signal in (usually ground) and signal out. The computer sends a signal to the transistor, and when its grounded 12v comes out the other side. So if you've got 12v, and a ground signal, but no flashing 12v coming out, you need an ignitor chip. This just happened to my KA the other day. I drove to the store, shut off the car, went in to buy smokes, came out not 2 minutes later, and it wouldn't fire up. I was SO pissed. It was my power transistor.

checked igniter, gonna find another one to see if its the problem.

most likely found the problem

[I build motors all day]

Ecu if its not that igniter

[HungryHank]

i already found out the problem

sparks weak and fuel is weak as well

fuel pump is dribbling gas like when you finish pissing and I need to get new spark plugs/fuel pump/filter

yaaa...
lemme swap it up and seew hats going down

Yeah I cruised over tonight and took a look - spark's there, just weak (but it's still "white" not "yellow", and definitely visible, which to me says that's not the problem) - fuel pump is priming, but didn't feel any pressure in the line, so I pulled off the filter and hit the pump ground, and it barely flows anything. My bet is, that's the problem.

Hank's gonna replace it tomorrow, hopefully that'll be that!
