SOURCE: starting problems

I believe this could also be due to a bad evap cannister or purge solenoid. Is the truck throwing any check engine codes?

you may need to get the fuel pump tested for proper voltage and pressure

SOURCE: 1999 5.3 vortec silverado 4x4. Engine intermitient hard start.

Had a similar problem and turned out to be a fuel regualtor.
Be careful with the little o-ring. Tricky little devil.
There may be residual pressure in the line so be careful you don't take a shower in gasioline.

It was hard to start after warm up. Rough idle until driving. Then on shut off it was hard to start.

SOURCE: 95 s10 blazer 4.3

Your blazer has to have 55 psi or better to start and starting fluild is possible to flood the plugs now their too wet to fire. Sit awhile and they should dry on thier own. The injectores won't past fuel below about 40 PSI while cranking the voltage to the pump or the pump ground is going away (starters not grounded good enought and the ground goes positive as the car cranks. Put jumper cables from another running car and coonect them right at the starter ( at least the ground, connect it right o the case of the starter, Pos/ can be connected at the battery). sure your battery may be toast and still crank a good starter but the voltage below 10 while cranking may not close the fuel pump relay al or the ingtion module. I've had this problem and sometimes I've found the ingtion module bad and I had it tested at the store and they said it was good but as I sent it in to be tested they sent a new one anyway and the new module would run it and the tested good old one won't start the car. BUT. Everytime it goes back to the quaily of the fuel pump and I've bought a lot of bad ones for GM products that were made by Master and Airtex. I've never had a problem with a Delphi. As long as the crank voltage is good jump it to make sure and the pump wire while cranking is more than 11 volts and it still has less than 55 PSI you take the pump back get another one or demand the delphi, and if they want you to put in another aixtex ask them to pay you to put it in. Bet you'll get the Delphi. The return level is high on the Airtex and Master pumps is high and the parts guy your buying from knowns this unless he's still wet behind the ears, and plain just does'nt know. Orginal equipment in this area keeps the comebacks away and I'm a pro. unless the customer makes me put in the junk pump I don't even give them a choice.

My 2003 Chevy Silverado's engine died while driving, engine will crank but not start


The battery starter and alternator would only affect cranking.
Someone will need to find out if it is spark or fuel related to know which system to inspect.

My 1992 GMC Truck C1500 1/2ton P/U 2WD 5.7L TBI 8cyl dies as soon as it starts. If I hold the throttle it dies. If I lightly pump the throttle, it will putter a while before dying. Two years ago, something...


Try changing the MAF. Mass air flow sensor on your air intake . I would suggest an auto wrecker, in case that isn't the problem, but that is exactly how they behave. I would imagine you have already changed the fuel filter?

You can shut off the regulator by removing the return line and blocking the return port. If pressure returns, replace the regulator. If still no pressure, check the fuel filter. Is there pressure behind it? If you remove it, can you blow thru it from behind? If the filter is not blocked, replace the pump.

What is the fuel presure? on a vortech engine the presure needs to maintain 60-66 pounds. It is possible that the fuel filter is restricting the flow of gas or could also be a weak pump... just a another thing to check... hope it helps.

Sounds like you need to get the Starter Solinoid Replaced. Just for Kicks make sure that you check EVERY Fuse and Relay in Both the Fuse Panel inside the Cab and the One Under the Hood.
