Change fuel filter and make sure pump is working. If fuel pump is working but is very loud you may need to replace pump anyway

I also had this problem with mine. There's a main power cable that runs to the battery. The bolt was completely corroded, so there was no connection = no power to start the truck. Check that, it'll cost ya less than 5 bucks to fix.

Hi,
I don't know what year, engine etc... but I can offer an idea or two for some basics:
1. Make sure your firing order is correct.
2. Check your timing.
(If you think good, make sure your not 180 out.. in case you pulled the distributor earlier)
3. Check compression. (I've had vavles stick before)
Hope some of this helps... Good luck

SOURCE: approx.50# fuel pressure at test port, engine will

I worked on a 1999 Suburban a couple weeks ago, it had good fuel pressure and spark but wouldn't run. No check engine light. It turned out the catalytic converters were plugged. After I took the exhaust pipes loose at the manifold it started right up. Just a thought.

SOURCE: I have a 1989 GMC sierra 4.3 Liter, fuel pressure

u can do the check the other way around/ disconnect the fuel line that supply the injectors/ put the pipe in a small plastic container to see if fuel is being supplied by the pump and avoid fuel spill in ur engine/ crank the engine for at least 5 seconds see if the fuel squirts with pressure/ if it does then ur fuel pump is ok / blockage is somewhere down the fuel line/ u can check fuel lines by blowing it with air but u gonna need the help of an air compressor.....

1992 Chevy Astro won't run, will start up great with starting fluid, or let it sit overnight.


You need to check the fuel pump pressure and I would change the fuel filter in the process. Sounds like you may have a bad fuel pump.

2000 Dodge neon starts and runs fine. But sometimes does want to start Engine cranks, but won't start


How many miles on the car? Have you checked the fuel pressure when it doesn't want to start? Do that first and then move on from there. To quickly test fuel pressure with no special equip get a can of starting fluid from the auto parts store, when it fails to start spray the fluid into the air intake of the engine well it is cranking, if it fires up then the fuel pump is likely not running on for some reason. This can be electrical in nature or just a failed electric fuel pump

Have a1998 astro van that wont start until I spray starting fluid in the throttle body, then starts up and runs fine until about two hours later I go to start it back up and it wont start again.PLEASE HELP...


The first thing you need to check is fuel pressure. This type of fuel system requires a minimum fuel pressure of 56 psi to start. Anything less, even as little as 1psi. And it will not start. It starts and runs when you add the starting fluid because the poppets (the mechanical injectors located at each cylinders intake runner) require less fuel pressure to operate when the intake is under vacuum.

This is a classic symptom of low fuel pressure. A new fuel pump is the typical fix for this problem. Don't skimp on quality if you do need a new fuel pump. They are not all the same.

Signs of a Bad Fuel Pressure Regulator
the vehicle will not start, if a bad regulator. Usually, this is a problem that is encountered in the morning when you start your vehicle. Many a times, the engine starts, but stalls shortly after starting. check the fuse and relay for pump. also remove line to fuel pressure regulator and if fuel in line, replace fuel pressure regulator. check for spark and also the timing belt. its one sign of not starting. if car runs fine on spray, I would not say its the timing belt or chain.

You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 63-64 lbs.
If you have all 3 then move on to injector pulse to all injectors.
I think each injector is on a separate driver on that one.
Check for pulse to all of them.

You may be weak on fuel pressure . Even a couple of lbs low on a cold start will cause a no start. Double check cold start cranking fuel pressure. If under 63-62 lbs you have problems.one test is to give it a squirt of carb cleaner not starting fluid. If you get a intake or engine full of starting fluid it can blow things. Carb cleaner will start it if it is a fuel problem and lot safer. Also in the good old days when i was a kid, i used to get a couple of cans of starting fluid and get in the back and have a good starting fluid spraying contest. Good for a big blast if someone lights a match. If it starts then you have a fuel pressure problem. Run the full fuel pressure test and post back pressures.

Here is the guide lines on testing.
Hard to start cold.
Check cold start fuel pressure.
Check engine running fuel pressure.
Check engine running on the road fuel pressure.
Then shut it off and watch for fast leak down.
Pinch off at rubber part or block off return line and check full pressure.
V8 gm engines should have 60-66 fuel pressure.
Cold start should be 64-65 lbs of pressure.
If you do not have full fuel pressure on a cold start the injectors will not squirt fuel. Do not leave home without it.
Engine running should be 60-66 lbs pressure depending on engine load.
Full pressure with return pinched off should be 75-85 or more.
And if it has a fast leak down after shut off you have a leak.


The 75-85 is only a check on the capable full pressure of fuel pump.
If you can not find the rubber return line check full pressure by plugging return line or just or the true full pressure can be taken direct at the end fuel filter.
What are the pressure readings that you have done.
What are your cold start pressure readings?
