    It will start and then runs out of fuel and dies . . takes a good minute or two of cranking before it will start again. Its fine as long as it doesnt sit more than a few hours.

Most common cause is a air leak into the fuel system at the filter bleed valve.

    Yes that is a common failure, we used to replace those pumps like they were going out of style, I worked as a Ford tech for 30 years, retired in 2003

    Check all the fuel line connections from the pump to the engine, the injection pumps can cause this to, that paticular pump did have some issues on high mileage engines.

Problems starting in cold weather: I have a 2004 trailblazer. Wont start on 1st crank, starts on 2nd. I replaced the battery. Any other suggestions thanks


The two most common causes are: fuel pressure leakdown after sitting for a while and an engine coolant temp sensor. The culprit is a leaking check valve in the fuel pump. To test, turn the key to ON for 2-secs, then OFF. Repeat 3 times. The try starting. If it fires right up, have the shop do an overnight leakdown test. If the fuel system loses more the 5-8-psi overnight, then the pump must be replaced. Test 2 is to check the engine coolant temp sensor. A sensor that's off usually reports a warmer engine than actual so the computer provides too lean a startup mixture. Try depressing the gas pedal halfway. If it starts right up. have the coolant sensor tested.

Why will my 1998 chevrolet cheyenne not start unless primed after sitting overnight


by primed are you supplying a fuel source if so then the car is not getting fuel to burn. this indicates your fuel pump is bad and needs replacing and change the fuel filter also. the reason the pump won`t work sitting overnight is that the pump can`t build up enough pressure possibly because the fuel pressure is not being held, but after the first start up the system can maintain enough pressure to start through out the day. you can have the fuel pressure and volume checked with a gage when the problem occours to verify.

My suburban has to be primed to start


There is a separate circuit and relay that primes the fuel system when you start the vehicle. If you sit in a silent location and turn the key to the ON position (without cranking), you should hear the fuel pump run for about 5-6 seconds. This is to bring the fuel pressure up in order to let the vehicle start. Then the normal pump circuit takes over. Sounds like your priming circuit is not working. I would try the relay first.

1999 Nissan Maxima, after sitting for a while the engine will start and run only for 1 or 2 sec then engine stops. Try to restart but engine just cranks, will not run. thanks, Roy


you either need fuel filter replacement or fuel pump. filter should be under the passanger rear in front of rear tire on frame rail, fuel pump is in the gas tank the tank needs to be removed for replacement i would try the filter first there only about 20 or 30 dollars and pretty simple to change

Dodge Dakota doesn't start on first attempt. Seems like fuel takes a while to get up to engine. Once started it runs fine. When it sits for 10-15 minutes, I need to crank engine, wait 1 sec, then crank...


Is the pressure in the fuel system not holding? Fuel pump may be failing or the filter may be bad. Sounds like you're pumping the fuel system back up to pressure before the truck will start. Like when a fuel-injected car runs outta gas and you have to prime the system before it'll start again.

When starting car, takes 8-10 sec to turn over.


Do you mean 8 to 10 seconds to START? Turn over means the engine is turning or cranking BUT starting is when the engine is actually running. I think you might have a fuel problem like your loosing your prime. Turn the key off wait 15 sec. then turn the key ON not cranking it repeat this (3x) if the car starts immediatedly your fuel pump is loosing its prime or the fuel pressure regulator is leaking.

87 VW Cabriolet starting problems


I would start with a fuel line psi test. then have your fuel acumulator.

http://home.hiwaay.net/~langford/CIS.html

check this out and see if it helps. It sounds like you are priming the psi up when cranking then it can go. but when you let it sit the pressure drops and has to build up again. I a not a VW person myself but love tinkering, so let me know how it goes.
