Started my car today for the first time since this cold weather has moved in and the car would hardly idle without dying and when it would start to idle it popped & it sounded really deep in the motor when it popped. Like detonation when it popped. I shut the car off. weeks & it just Mods are as follows

Tuned on Mass Air
TFS Heads
Fast 90/90
42lb injectors
Vengance Vinticator Cam
Auto

Came out the next to day to start it & now it wont start. The car turns over. It sounds like it wants to start. But just wont.

I think its a fuel problem. But im not sure? Any suggestions on where to start looking

What size injectors were in it before u put the 42lb'ers in? The car shouldn't have been started if it weren't tuned for it.

Car has already ran 7.1 @ 96 on this motor & injectors 3 years ago. But I lost the trans 3 years ago & since I still had reverse I just put the car up & focused on other things in my life. But the car was tuned on Mas Air by Chuck at HPE in Houston. Car has just been sitting for the past 3 years & started once every month. This just happened when I went to go start it & let it run this month

I dont understand why all the sudden it started to detonate & now it wont start. It trys to start. You can hear the motor want to turn over.

The condition of the fuel is suspect - do you use a stabilizer?

The fuel is fresh & it idled great 3 weeks before when I started it & let it run on that fuel.

This happened all the sudden this weekend out of nowhere. Its like the fuel pump just took a ****. But I hear the fuel pump prime when I turn the key,

I wonder if I fouled my plugs out & thats why it wont turn over

Ok I pulled all 8 plugs & they smell like gas & are Black at the tips. Putting in fresh plugs. Anything else I should check while I have the plugs & valve covers off

Put a gauge on the fuel rail and check for pressure at idle. See if it bleeds down immediately, slowly over a few minutes, or not at all (should be around 58psi). Also, disconnect each injector's harness and remove the fuel rail a few inches above the intake (but leave the fuel lines connected). Have a buddy prime the car (or if you're alone, put paper under each injector tip), and check for leaky injectors.

FOULED PLUGS!

Went & put in new TR6 Plugs & fired right up & idled great with no detonation.

congrats,but weird. were they old plugs to begin with?

Yeah they are the same plugs that have been in the motor when it was rebuilt 3 years ago! But I think starting it & letting it run might have been my bad move. Just sitting there & not reving out it was just soaking the plugs with fuel
