so i know for sure know that the fuel pressure is good, the timing is good, spark is definite and using a msd 6a, getting air etc. it started when i had a fuel pump switch because i could jimmy it. but the fuel pressure was off

but now it wont without the switch and with correct fuel pressure. the car sat for three years and has alot of crap it needs to burn off. could that keep it from idling or starting easy???? im getting ticked. its been 6 months o hell with this car.

 

I say you try and tow start it, that usually will get it done and get teh engine set in enough to run on it's own.

 

What happens when you spray starter fluid in the intake? And, have you cleaned your injectors? My car wouldn't start after sitting for over two years, and it turned out the injectors were gummed up, and not spraying fuel. Also, you didn't say anything about the voltage at your injectors--do you know that you're getting a signal for them to spray?

It seems to me that you've narrowed the cause down to a no fuel condition, so two good tests would be to: 1) ensure that your fuel lines are plumbed correctly, and 2) pull your primary injectors and fuel rail, and perform the injector volume test on pages 4A-71 (or 4B-74) of the FSM.

Finally, I'm assuming you have compression. If it turns out that fuel delivery isn't the problem, then you should check your compression. Maybe you could try a small amount of oil in the leading spark plug holes, just to momentarily boost it (?)

Here's a thread that I posted when I had my starting problem. It may give you some ideas: https://www.rx7club.com/2nd-generation-specific-1986-1992-17/ecu-outputs-troubleshooting-s4-no-fuel-problem-391497/.

Good luck!
