Default No Start 97 4.2.

ABZ. Replaced Fuel Pump, crank position sensor, fuel pump relay. Have lots of fuel at return line. Spark. Handheld vagcom 401 shows no fault codes. Fresh battery. New coil packs. Swapped known working ECU/M. Still no start.

If car sits for hours, it will start for a second.

Background: Purchased car a couple months ago. Mileage 160k. Hasn't been on the road since 12. Old gas, but started. Ran rough. Added fresh gas, ran vagcom, 3 bad coil packs. Once packs replaced/codes cleared, the car ran really well. Took for a 10 minute drive, and the car died. Discovered bare wires at the cps, Drained tank (still had bad gas). So replaced pump and filter.

What should I check next? Thank you.

Injectors might be plugged, try a puff of starting fluid maybe.

If it starts after sitting for hours it might be too rich, hosing or dripping injectors. Maybe disable the fuel pump and try to clear a flooded engine, then try reconnecting the fuel pump for a few seconds or starting fluid to see if it'll catch.

Interesting. Thank you. I'll try that later today.

I'm getting no start with ether. Here is a pic of the timing belt. Have not checked timing (no crank wrench handy), but all looks okay except the position of the tensioner shock. Is this normal. Is there something that caps the top pivot? Given no start with the fluid, i think it might be spark or timing.Any more suggestions? Thank you. Michael
