Sounds like a fuel problem. If it runs when you spray carb cleaner your "fuel" may not have enough octane. I suspect you could have 50psi with a high water content (or the wrong fuel i.e. gas vs diesel?)...Drain the fuel and replace with fresh fuel (gasoline or diesel depending which engine you have), along with a bottle of fuel conditioner.

FUEL PRESSURE MUST BE 62 LBS. OR GREATER OR IT WILL NOT GROUND INJECTORS, IF ITS OK THEN CHECK YOUR GRAY 12V SUPPLY TO PUMP AT CRANK-UP, YOU MAY HAVE A POOR IGNITION SWITCH.

Having good fuel pressure is a plus (yours seems a bit high but I don't have specs) What you need to find out is if the injectors are opening and putting the fuel into the engine so it can work. Are the plugs wet with fuel or dry? Does it fire up if you spray carb cleaner into the throttle body while cranking?

It does sound like a fuel problem, try running some jet cleaner through as you may have clogged jets. Sometimes, removal of air filter and placing the palm of your hand over the top of the carb's butterfly valve, will clear blocked jets when engine cranked over a couple of turns.
Also check the float valve is letting fuel in, could be stuck.
I hope this helps.

it is possable/likely a bad ECTS (engine coolant tep. sensor), this can cause the injectors to allow to much fuel into cylinders and cause a low compression and or flooding situation, good luck, marty

2000 chevy surburban 1500 will crank but no start. waited one day then started. Ran for a week. Stopped again. Waited one day no start. Waited three days started again. Any suggestions??


more than likely your fuel pump went out. it's in the tank. you can try spraying carb cleaner in your throttle body and have someone crank it. spray small amount of carb cleaner beware of backfire. do not acclerate while cranking. if vehicle turns on its your fuel pump

What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!
