I've got gas, I've got spark... why won't the car run

[PBK522]

1990 K5 blazer, gas, 350, fuel injected

So my truck won't start.

I've got spark. The injectors in the TBI are spitting out plenty of fuel. I'm cranking beautifully

any ideas???????????

Is the timing set right?

Well, all I can think of is a timing problem. Having spark isn't as important as having spark at the right time. Have you been fiddling with the distributor at all?

Maybe someone who knows how to troubleshoot an EFI truck will stop in and have some better feedback.

DOH!!! Beat me to it, brother.........

How can I check the timming. I haven't fiddled with the distro

You're gonna have to get ahold of a timing gun and check the timing.

What kind of work were you doing on your truck when the no-start issue surfaced? Did it just start happening right out of the blue?
