SR20 Redtop Starting Problems...

[ninja323]

Well I was driving around and my SR20 just dies on me.. I was only going like 20mph and it just cuts off...

I try to crank the car back up, it keeps turning and turning but won't turn over... So first thing I do is check all the fuses, no blown fuel pump fuse. I had one and that was the Eng. Cont. one (25-A fuse), I replaced that and still the same thing..

I have a Walbro 255lph fuel pump, and now when I turn the ignition with the key in, you can't hear the fuel pump coming on like usual. My S-AFCII would power up when the key was turned but now it just stays off..

I doubled checked all my fuel lines, and I/C lines for any vacuum leaks but nothing. I know my car is running rich so do you think my spark plugs could be fouled out? I would check but I don't have the tool for it over at my parent's house. But the thing is, my S-AFCII isn't powering up so I was thinking it could be a loose ECU connection or just that my ECU went bad?

What else could I look/check for?

Your MAFS connection isn't getting completed since your AFC is off. Recheck the power and ground connections for the AFC before trying again.

I think the power connection is fine but unsure about the ground, may have came loose...

But what about my fuel pump not priming/getting power?

check the blue harness that couples to the ECU first. Sounds like there's more going on around there than you might suspect. If not there, check the fuse for the fuel pump. Double check the connections for the AFC, and do not get the order of the brown and black grounds for the AFC mixed up.
