Car won't Start need help diagnosing it

[OneJArpus]

Ok well look at my cig for mods. All installed but cams.


I got the car done two weeks ago. I've put 400 miles on her so far. I went to work with her on tuesday she was running good. I went to leave work and she would just crank and not start. I need help diagnosing the issue.

How would i check if the ignitor is good?

How would i check if the map sensor is good?

How would i check what FP i'm @. I'm using a walbro fp with the stock FPR

ECU has already been checked and swapped out and still doesn't start.

I also have the 12v mod.

What would cause the car to run perfect but not start? As i said before it was running good the 400 miles i've drove it for its break in period but now its just cranking over and won't start


Cliffs: See cig for mods, car drove good for 400 miles now it cranks over but doesn't start need help. Thanks!

I just want to drive her again! 3 years into the project gets done n now this!

PS. I've been searching the forums with no luck as of yet and while i still search i figure i start a thread

well u can hear the fuel pump run with u crank it. since its a stock pump u might have to open the gas fill and have someone listen for a hummmmmmmmm.

and i dunno how to check those other parts sorry

Stock system other than a walbro fuel pump and 12v relay mod.

mine used to do that alot and it was always the ignighter connector. i would just unplug them and plug them back up and it would start right up. also had a similar problem and it was the wiring to the mass air flow. one of the wires broke at the connector

problem solved

ended up being a super simple fix lol. Bad ground on the battery to the body. Once i changed that wire and primed the fuel system it started right up.


10 bux for a new cable to prevent a bad ground. thanks for all your help
