88 5.0 won't run - Page 4

When it fires up, does it run rich and pop back through the intake? If it does, check the MAP sensor.

Yeah....

We assume the car is speed density instead of mass air?

It is speed density.

Is the new computer SD, or mass air?

Throw all that fuel injection crap in the garbage and put on a carb with a MSD 6AL!!!

did you pull the dizzy out, check the gear, realign the dizzy at number one cyclinder and make sure that #1 cylinder is at top dead center with timing mark on balancer at 0 degrees?

Is the battery good, good cables and connections on them too (I am sure you have checked).

Any major vacuum leaks?

New distributor and pick up. Distributor (the old one and new one) is in with # 1 up and at 0.

Not that this is the problem but when I install a dizzy, I put it
TDC compression stroke on #1 go to zero and then back it up
to 10 before TDC and they always crank with no adjustment
needed.

it should drop fuel psi while starting right?
