I’m in need of some help I have an 88 g20 shorty which is a full restoration when I got the van it was a no runner and was being sent for scrap. To get it in running condition I had to put in a starter,alternator and battery that’s when the problem solving started so I ended up having no fuel from injectors so I replaced injectors rebuilt the tbi new oil sending sensor distributor and ecu and it ran really well then last fall I had it towed to a storage for the winter this spring towed it to the shop thinking it should still start and nothing I wasn’t getting fuel again so I replaced fuel pump and fuel filter nothing so I replaced the fuel pressure regulator spring and I have fuel and injectors have a nice spray it started then a couple days later went to start it nothing now I have no spark so I replaced plug wires and spark plugs it fired right up I left it idling came back it’s not running and won’t start again so now I have replaced the map sensor the ERG valve and EGR Solenoid the PCV the ICM even tho it was new with new distributor the ignition coil with a MSD street fire coil pulled the distributor and reset it at TDC I have all my vacuum lines capped off and tested compression which is as follows cylinder 8 150psi #6 160psi #4 160psi #2 150psi #7 155psi #5 160psi #3 150psi #1 150psi
I have spark and fuel my compression is good but I did pull the plugs and # 2,4 and 3 were soaked with gas and the rest are were covered with black soot so I cleaned reinstalled disconnect the injectors and poured gas down the throttle body and nothing not even a shudder I have no idea what the problem could be any thoughts or ideas would be very much appreciated

Hi, welcome to the forum,

Posts are extremely hard to read with no spacing and little punctuation. I skimmed over it and didn't see any reference to the CTS / ECT (coolant temperature sensor) - if your plugs are sooty and wet with fuel your CTS may be bad and causing the fuel mixture to go full rich and foul the plugs out.

You can test the CTS (check our FAQ pinned at the top of the forum list for info) but if it's old, you may as well get a quality replacement as they are not expensive and they do go bad.

I would also pull that MSD coil and put your stock one back on if it's good. The MSD's rarely last long.
