Will not Start :(

[JamesRHayman]

My 91 non-turbo R/T will not start and I cannot figure out why, can anyone steer me into the right direction

I pulled a couple different plugs, they have spark, and seemed to have fuel on them from trying to start it...It started one day, and then nothing the next???

It cranks fine, but does not seem like there is any amount of effort to fire, no sputtering or anything.

thanks for your help in advance

Hmm... If you're cranking, getting fuel, and spark, and sometimes starting and sometimes not, then I have to suggest popping open the ECU and checking the caps. These sound like symptoms I had when mine were toast. It's pretty easy to check too.

[JamesRHayman]

pardon my ignorance, but this is the easiest way to find out, so where is the ECU, thanks

Behind the shifter, under the radio. It's held in by 3 12mm (10mm?) bolts and will have 3 harnesses plugged into it. Remove the carpet on both sides of the center console to do it. Once you've done it once you can literally pull the thing in 5 minutes.

Since you're a 91, if the caps haven't been replaced yet they need to be. Even if they aren't leaking.

[JamesRHayman]

if they have started to leak, is it necessary to change the whole unit or would installing new caps still solve the problem?

[lawdogg]

Installing new caps would solve the problem assuming your caps are the only thing that went bad.

[kylejw]

Though sometimes the fluid that leaks, which is corrosive, can damage other parts of the board. There isn't really a clear answer but if the leakage is small it should be alright

Check for spark,fuel and compression(timing)
If ok, go for ECU
