1990 suburban v1500

[Truckdriver09]

Hi, I have a 1990 suburban V1500 5.7L. The truck has sat for a couple of years without being started because the thread on one of the fuel fittings was stripped out and needed to be chased, and I was out of state for a couple of years. I got back and fixed the fitting. I had to replace the battery because it was old and not holding a charge. I also poured in 5 gallons of 93 octane gas and some seafoam into the gas tank. I go to turn the key and all I'm hearing is the click of the starter solenoid, I figured there might be some corrosion because of hurricane isaac and there was lots of flooding and the water level almost reached inside of the truck. Turns out the nut for the power was just loose. Tried several times to get the truck to start and just wouldn't start. I figured it wouldn't start easily after sitting for a couple of years. However I had my wife crank the truck while I looked at the injectors to see if any gas was spraying into the motor, I was only seeing drips, no sprays or mists. Sorry for the long post, I figured it would be best to fill everyone in. I'm suspecting there might be a clog somewhere or the fuel pump is not pumping with enough pressure and I wanted to get some insight from others on the issue.

Thanks!

One thing you might try - while your wife is cranking the engine, bang on the bottom of the gas tank with your fist - quite hard.

If the fuel pump is going out or jammed from non-use, this will often break it loose and the truck will start.

Another thought is fuel filter, although it could also just take a while for fuel to reach the TBI after sitting so long.

Good luck!

Just turn the key to the on position, you should hear the fuel pump cycle on then off once pressure is reached. Of course if it is hard to hear you can take off the gas cap and put your ear to the filler neck and listen. check fuses as well..
