I have an 88 GMC 1500 RCLB. Put new Delphi pump in 2 mos ago, along with a bunch more restoration items.
Just put new alternator in; Truck was running great; I had about 1/4 tank of gas, and just filled it up. It sat for a few days without being driven, and I am in N Texas with temps over 100.
Put new alternator in and drove to the shop to return the core. Got back in truck to leave and it wouldn’t crank. Would turn over, but wouldn’t crank unless I sprayed carb cleaner in carb.
Checked fuel pump fuse and relay and both are good;
I think my fuel pump went out;
Could it just be coincidence that the pump went out after only 2 mos?
A guy at the shop looked at it and asked about the gas. He actually called it and said he was betting that I just filled it up, and even asked if I got gas at racetrac, which I did. He said something about the high ethanol gas combined with filling it up and sitting in hot temps prob caused vapor lock and fried the fuel pump.
I am admittedly a newbie to all of that; but does any of that sound accurate? He said those old motors weren’t designed to run off of high ethanol, so he would suggest putting an additive in every few tanks.
I am just wondering if I just got a bad fuel pump, or if it is related to something else. It was running great until it wasn’t, and then wouldn’t even start. No warning!
I plan on tilting the bed up tomorrow or Tuesday and get a closer look at the pump, but just wanted to get feedback.
Thanks!!
