S-15 starting problems

We have a 93 S-15 with the CPI 4.3. REcently, in the mornings, it will crank, gets fuel, but won't start. Turning the key all the way off, then back on a few times seems to do the trick. My first thought is ignition switch, but father in law, a 25 year GM parts guy, says that coils in those have a habit of flaking out in the cooler weather.

Anyone out there deal with this?

Thanks.

so does the fuel pump

Thanks folks...a new AC/Delco fuel pump solved the problem.
And for the record, it's not too hard to change in a S-10/S-15. Backyard mechanics its about a 5 out fo 10 in difficulty.

Does Anyone Know Of A Site With Schematics/drawings For Locating Devices

Don't you have to lower the gas tank to do the fix? I've heard it's a pain. Maybe thats only in the newer vehicles though

I changed the fuel pump in mine and the major problems that I had was the bolts for the tank rails that hold the tank in where so tight I couldnt hardly get them loose.I have a really nice impact and it took alot of banging and lubing to get them out.Also the gas line fittings where gone.They where pretty rusty.Once you get past that its not a bad job.
