After coming back from a month long training event, my truck started running & ideling rough with loss of power. (Stalled once switching from parked to drive). I replaced the sparkplugs, wires, distributor cap/rotor later that week and the truck started/ran but with the same issues. I then replaced the ignition coil, & ignition control module later that week, double checking all the work and now the truck won't start and/or stalls. I faintly hear the fuel pump when I turn the key but I'm not 100% sure. I plan on replacing the MAF sensor and fuel filter next before I attempt to drop the gas tank/fuel pump or get screwed over with a mechanic's bill. Any help would be greatly appreciated.

Unknown engine mileage from previous owner.

 

A 91 should be TBI right?

My 94 didn't have a MAF sensor, so shouldn't be that.

Spray brake cleaner or something into the throttle body and see if it stays running. If it does, you have a fuel supply issue.

 

fuel still smell good? I had fuel turn on me in a week one time. Nightmare. I had to drain every damn machine I put it in.
