Off Topic : Farm Truck (Chevy)

fatbob50 · Jan 19, 2015

I have a Chevy that I use for a farm truck. It is a 1992, half ton, with a 350 engine. It is an automatic and has 4WD. I had the automatic transmission rebuilt and when I got the truck back it started and ran good. The transmission is good. But 3 or 4 days later the truck would not start. I do not know if rebuilding the transmission had anything to do with it or not, but when you turn the key on, the instruments and light come, you can hear the fuel pump, but it will not start or turn over. When I short out the solenoid on the starter, it starts right up and then goes dead. I changed out the ignition switch and that did not help. Any ideas or suggestions would be appreciated. Thanks in advance, Bob

Check out the neutral start switch. Try putting it in neutral instead of park.

This could be a linkage problem and the trans shifter is not contacting properly , try staring with shifter in neutral..just an idea that I have encountered in the past.

It will not start in neutral. Thanks for the suggestion.

"When I short out the solenoid on the starter, it starts right up and then goes dead."

OK - I think that truck has fuel injection and electronic ignition. Your symptoms remind me of the dead ignition circuit that will only run when the starter is engaged. I don't know if the electronic ignition works like the old point system, where the starter circuit shunts the ballast resister and boosts the voltage to the ignition while starting. John T. or Bob or maybe even Buickdeere can tell us if that could be a possibility.

I'd say it is just a coincidence, start by checking alternator charge voltage is at least 13.5. If so get the battery load tested. The direct jumping at the starter may just have enough extra apply voltage without the resistance of the wiring and switch to still get the starter to crank. Most likely need to replace the starter if above items check out. I'm sure everyone who has done mechanic work has been blamed for stirring the pot of "Murphy's law"!

Edit: I looked at your post again and I see I missed the part about it dying again. So that is not caused by a bad starter. I think the computer still reads engine oil pressure to continue fuel pump operation after a start cycle. So maybe check the oil pressure sending unit. If I'm wrong about this maybe someone will chime in.

Nut not tight on the big post of the starter-solenoid? Common problem on Chevys of the 70s-90s.

I have seen the neutral start switches get out of whack where you almost need to have it in reverse or drive to start.
