SOURCE: gas not spraying at throttle body

replace the injector - before you do that test voltage going to the injector- is should pulse on and off to open and close it

SOURCE: 1996 suburban wont start.

first you have to measure the fuel pressure with a guage, pre start and cranking, it should stay approx thesame, next check for injector signal to the injectors , use a noid light,

SOURCE: 6.5 turbo diesel wont start

check the high pressure oil switch next to the glow plug controller. if the switch is bad you will not get any fuel to your injector pump. unplug the molex and jump it out. this will bypass the switch. if it runs, just buy another high pressure oil switch. good luck!

Our mountaineer is getting gas into the oil. What could possibly be the problem.


Fuel pressure regulator. or stuck open injector/s. The only way gas can reach the oil is threw the piston rings. Gas will seep threw them. regulators can dump a lot of fuel threw the plenum. An open injector will bleed off pressure(when turned off)) and dump gas right into the piston.

Car wont start


could be few different problems first u need to check for fuel pressure and spark
hook a fuel pressure gauge up and see if ur getting any fuel pressure if you have no fuel pressure u either have bad pump or out of gas (don't laugh i had cars come in shop for a no start that where just out gas)
if u have fuel pressure
then check for spark
take one spark plug wire of a spark plug and hold wire about 1/4 inch away from either the spark plug or engine block if u see a spark or hear one
if you have no spark your looking at a few different possibles Bad coil, ignition module, crank sensor, etc
if you have fuel pressure and spark but still no start u need to check for injector pluse (basically computer telling fuel injectors to open)
but now i think I'm getting over your head let me know if this helps and i try to walk u threw other things if this dont help

I replaced a fuel injector on my 95 Cavalier and now it wont run


Use a gage and check proper fuel pressure, 41--47 psi, key on engine off. Cycling the key on and off a few times before you crank it, should prime the system.
Check for fuel injector pulse, use a noid lite, engine cranking. The voltage for fuel injector probably goes hot with the key on. The computer grounds the fuel injector circuit. The diagram is for 2.2L engine. The pink wire for fuel injectors is voltage, the bottom wire is ground. We've talked about the fuel system, could be other issues?

i'm pretty sure you have a Central Port Injection setup on this engine. Which means the injectors are inside of the upper plenum and cannot be seen. This type of fuel injection system uses a centrally located electric fuel injector(s) which feed fuel to a mechanical poppet style injector which is routed directly above the intake valves for each cylinder.

The poppet valves require a minimum of 56 psi of fuel pressure. If you have 55 psi it will not start. It needs the fuel pressure to overcome the mechanical resistance of the poppet injectors. Fuel pressure should at least be 60 psi. It is very important to check fuel pressure with an accurate gauge.

If fuel pressure is low it will not start no matter what you do and a new fuel pump will likley fix the problem. Get a good quality pump such as an a/c deco or Dephi. Other brands may be cheaper but they will not last.

If fuel pressure checks out good let me know and I'll give you some more info.

1995 chevy silverado 350 TBI V8 standard powerloss


have you checked the filter, i know you state the fuel lines are clear though. likely fuel injectors have lost flow. the TBI injectors can be cleaned, but i usually just replace them. but check them using a timing light hooked to the coil wire for timing of each injector spray. the pattern under the light should be even and conical shape, no major spatter. if one shows low volume, the other one should be replaced at same time, it will save you having to change it when you put brand new next to old one a have same problem again. only replace with brand new, i've had 7 bad remanufactured injectors on one truck at one point in time, only replace with new!

Make sure the central injector is not leaking( fuel pressure should hold ) the cfi is alot of plastic and it's inside of the intake maniflod(they crack and leak!) part about 350. How do you know the computer doesnt work

Do you have spark? If you do sounds like a fuel delivery issue. Check fuse for fuel pump, you are in a later year and should have an electric fuel pump. If you are getting fuel to the injectors at correct pressure you may need new injectors.

Try starting with starter fluid if it catches that will secure that it is a fuel delivery issue. If it doesnt you probably dont have spark and most likely be an ignition module.
