1998 GMC Express van non starter

[CrestaMan]

Hi all,

I have recently bought this van from from a salvage yard (minor unrelated cosmetic damage) as a non runner. It refuses to start even with a shot of easy start in the air intake. There is a good spark at the plugs (no cross sparking) but still it don't even try to fire up. The previous owner said it just died whilst moving it a few days after the accident (ran for about 5 minutes). The fuel pump can be heard running and there is a strong smell of petrol after it has been turned over several times.

It has the V8 5 litre fuel injected petrol engine.

Any ideas as I would like to get it running for the coming show season.

Regards

CrestaMan

It may sound silly, but try new plugs.

Check fuel pressure. Pump might be running but may not have correct pressure to open injectors.

X2 on the fuel pressure. The GM EFI requires 40 PSI minimum. A sudden non-start is frequently due to the in-tank fuel pump going bad. A fuel pressure gauge on the test port will tell this quickly. If you have fuel pressure, other possible problems are a stuck-open injector or a bad crank position sensor.
