im having some issues my old 5.0 in my 1989 gt wasnt running good and my dad had a complete with accessories 1994 5.0 that i could have so i swaped and put my 1989 upper and lower intake on the 94 block and kept the 94 accessory set up and put it in the car. i started it up started first try didnt even hestitate was running a little rough so i hoped out amd moved timing back towards 10-12 with my timing light now but i had to leave for work so i ahut her off and left came back next day and now 3 days in a row wont start ive cleaned grounds new battery new distributor new ignition coil new spark plugs and wires new tfi cap and rotor and fuel pump im so puzzled. i have fuel preasure 40ish psi but no spark. i though it was coil because the ohms it was giving were below what it was supposed to read didnt change anything then thought it was tfi or pip sensor so i got a complete distributor disnt chamge anything thought maybe fuel pump went bad because i didnt have fuel preasure but now i do have 40 psi i am so puzzled i drove the car the day i parked it to pull motor and trans the 94 motor i have in it now ran pristine with less then 100k miles on it eveything should be good i dont get it ? the car cranks really good it sounds like it wants to start like it right there. PLEASE HELLLP i live in michigan so if anyone has some time to possibly help hands on im always looking for some help/car friends if you wanna call or text me im available anytime 248-648-9887 Jake is my name hoghly approciate any help to get me back on the road im in agony shes not firing right up

Have you tried cranking the car with the gas pedal to the floor?

You mentioned no spark, did the distributor swap cure that problem or is it still getting no spark?

Pull the number 1 spark plug and verify TDC. ( sounds like you may have done that but always could double check ). Make sure the distributor isn't 180 degrees out.

Make sure number 1 is on cap in same orientation as pic

Run through the check list posted in #4

I didn't suggest your timing being out because you said your not getting spark. If you don't get spark you will flood the engine like your doing which is why I suggested starting the car with the pedal all the way down which disables the injectors for startup. Careful you don't wash down your cylinders and go back over everythign you touched or start ruling everything out one by one by using that check list. Also no plugging the smog ports on the back of the cylinder heads and deleting the EGR will not prevent startup but may produce a check engine light

When I did the H/C/I install on my car I had issues getting it to start and stay running. Sometimes it would start and die and others it wouldn't start at all. I knew it was the timing but I just couldn't get it close enough to start and stay running to set it. Finally I had my dad crank the car while I rotated the distributor back and forth to find a position it would start and stay running. Had it running perfectly in about 2 minutes.

I would suggest having someone crank the car while you turn the distributor by hand to see if you can get it to start. Of course verify that you are close on the timing first.
