There should be a 2 second prime by the fuel pump. This prime by the fuel pump is standard for GM vehicles, and if it is not present a hard start is encountered. Turn the ignition to the run position and listen for the fuel pump operation. You may have to have an assistant listen at the fuel filler by installing a long slender funnel into the fuel inlet to the tank, remove the gas cap and insert the funnel, listen at the large end of the funnel to see if the pump can be heard running. Using the funnel acts like a megaphone and makes it easier to hear the pump. If the pump runs for 2 seconds after you turn the key to the run position (DO NOT attempt to start the engine during this test) and the engine doesn't start due to lack of fuel, check for an obstructed fuel filter. (Just change it, it's probably overdue for service anyway since everyone thinks it get changed during oil changes, but never really does.) If the pump doesn't run during prime interval, the computer may not be turning on the fuel pump relay, or the relay is defective. To check the relay, use another of the relays in the power distribution box to substitute for the suspect fuel pump relay and retest. Be sure to wait at least 30 seconds between key cycles since some systems have a delay timer built in to keep the pump from over running. Be sure the relay you sub into the fuel pump socket is identical to the one you remove and properly oriented in the socket. The engine will run following your manual prime because an additional set of contacts in the oil pressure switch will power up the fuel pump relay once proper oil pressure is achieved by an idling engine. If you find that the relay is not defective, but doesn't provide a priming impulse, the engine computer may have failed. DO NOT use a conventional test light with a filament type bulb to check any of the computer circuits that drive the fuel pump relay, or any other computer controlled circuits on an automobile ( or pickup) The driver circuits in a vehicle computer can be blow-out by over-current when using a conventional test light. You can use a high-impedance DVOM for testing safely.

2002 Ford Mustang GT, CAR STARTS UP FINE WHEN COLD. Hard to start when warm No Check Engine lights come on.


Think about how the vehicle is acting. Starts fine when cold, hard to start when warm. In these computer operated systems, the computer runs everything. Starts fine when cold: the computer has the engine in cold start mode putting more fuel in till it warms up. Temperature sending unit in the manifold sends a message to the computer telling it to stop the cold start mode and it stops dumping excess fuel into the cylinders and it runs fine. IF, mind you, IF the temperature sending unit is faulty, it's not telling the computer to stop the cold start mode and is flooding the engine with fuel cause it's sill in cold start mode. This is my take away on your situation and the temp sending unit is something to check to be sure it's functional. Check it out. I hope this WAS the answer to your problem my friend. It's typical. Luck to'ya Bro.

How about the fuel pump...are you getting the fuel to the cylinders? Is the fuel making it through the fuel line through the fuel filter? Drop a few drops in 1 cylinder, if it fires, you have a fuel problem. Does it turn over? If not check out the motor starter!

Without any other symptoms it is hard to diagnose; could be water in the fuel or a plugged up air filter, that effects idle first, take it out and see if it idles fine, if so get a new one. Take out fuel filter and dump in a glass bowl and analyse for water... get a new one... Is it different when the engine i hot or cold?

The truck sometimes barely starts. then once it does, it idles fine. but when you give hard acceleration, it falls on its face. not the fuel pump or the filter, and definately not spark. its a 96 chevy 350...


Lets go back to the fuel pump. I am working on one now that has the same symptoms.It turns out it is the fuel pump. Still pumping fuel, just not enough pressure. Hard start, idles fine give it some fuel and dies. One other thing that I can think of that will do this is clogged catalytic converters.

If there is little or no vacuum going to the engine at time of start up that will cause the engine to be hard starting, what it does is since theres not much vacuum if dumps crazy amounts of fuel into the cylinders to aid in starting, also would cause it to run funky for a few seconds after its started
