    What is it you need to Know ? Does the truck have a carburator or fuel injection if it has a carb the fuel pump is on the engine if it has fuel injection it's in the tank before you change anything please test to be absolutly sure its that its too hard to change the intank pump and they are very expensive as I always always recommend Dealer parts they are the best don't worry about the cost but be concerned of the quality Dealer parts are better no question.

The Fuel pump is definately in the fuel tank not too hard to change but be careful with the plastic fuel lines, and make sure yu reconnect the ground wire like I said before buy your replacement at the dealer why mess around with a aftermarket copy that may not produce good service

94 s10 will not start without priming


Hi,
Most often when an electric fuel pump does not prime the vehicle correctly, it is a sign that the fuel pump is on its way out. Only solution is to replace the pump. I always change the fuel filter first and see if that helps before replacing a pump, as the pump is costly and harder to replace. (located inside the gas tank which must be removed for replacement.)

Please vote if this helped! Thanks, Mike

As a quick test,fill-up the tank and do not top off.

Monitor the starting problem.

If you're starting OK until BELOW 1/3 of the tank then it's a weak/failing fuel pump.

'94 S 10 Blazer V6 Vortec EFI. Fuel pressure good, new fuel injectors installed, fuel pump works ok. Only starts with starter fluid sprayed into air intake. Any Suggestions?


your statement is fuel pump work ok, have you tested for proper fuel pressure. just because the fuel pump works it could have less pressure needed to start the engine. maybe the fuel filter is plugged. start out by replacing the fuel filter, if this doesn't fix it, you need to pressure test the pump. even 10 psi reduction in pressure will allow the engine not to start.

When its cold my 94 Isuzu pick up leaks fuel i think from the fuel pump. Now it wont stay running while idleing. should i just change the fuel pump?


Yes you should. It will not get any better. The seals are bad and with the fuel leaking, it will only get worse.

Tied to solve problem why 1996 chevy Blazer won't start


They should be on seperate circuits. Tyour key on and ck to see if you have any fuel flow. Fuel pumps in tanks do **** out. chk to see if you have any fuel flow by loosening a fluel line. No fuel, no pump. good luck
