1988 Chevy S-10 4 cyl Two Wheel Drive Manual

Last night I was driving to a friends when all of a sudden my truck begin jerking as if it was losing gas or getting too much gas. If I baby the pedal it would go a little but when I gave it more gas it wanted to try to shut off. So I tapped the gas all the way to my friends house. It was backfiring also. Finally when I got it parked I floored it and it shut off. Now it will not start again.

Welcome to the forum, have a helper crank it, while you check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. Any trouble codes?

I've read about trouble codes but do not know how to obtain one. This model from what I read doesn't have an OBD.

If your computer controlled, there should be a datalink connector, lower edge of dash, close to steering column. You place a jumper wire between terminals A & B at the datalink connector. then, turn the key just till the dash lites come on, no further. The mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes. The picture below is only to reference A & b TERMINAL location. I sure thought you had a datalink connector? I've been wrong before.
