I bought a 94 blazer that sat for almost 5 yrs, replaced tank, fuel pump, filter ,injectors, plugs wires, plugs..injectors shooting gas , mother effer won't start


it is more than likely the cam or crank sensor. Do you have spark while cranking? if not check these sensors. Make sure the wires on top of the tank going to the fuel pump are connected and you have a proper ground. On these cars when you turn the key to the run position (just before starting) you should hear the fuel pump running for about 3 seconds Their could be many other reason s for it not starting but you need to start somewhere. Let me know I can give you more things to check if this does not work

Cranks well but won't start.


Looks like you got spark, and gas in the throttle body made it fire: nice work.
Sounds like your fuel pump is out or the wiring is not turning it on. One way to be sure is to set a spare battery near the tank and hot wire the pump with jumper wires. Or if you have a voltmeter check for voltage at the fuel pump connector while the truck is cranking.. If the pump is working and getting gas to the engine, see if the injectors are pulsing. A good idea to check fuel pressure if the pump is working.

I have a 2001 Explorer Sport Trak and it don't want to start. We have checked all the sensors (crankshaft, cam trigger, fuel pump pressre is 65). What is the tank fuel pressure sensor voltage reading. ...


The first thing to check would be spark. This can be done by connecting a spark plug tester to a plug wire while the engine is cranking. The tester must be grounded to the engine block for a good electrical connection.. Your fuel pump pressure is OK.
The problem should be electrical so check
1. No voltage to the fuel injectors (blown injector fuse or bad relay)
2. No pulse signal to the injectors from the PCM (no crank or cam sensor input to the PCM, or a bad driver circuit in the PCM, or a wiring harness problem)
3. A shorted fuel injector (robs voltage from the other injectors so none will operate)

2000 S10 no start


I'd use a gage and check proper fuel pressure, key on engine off, 60--66 psi with spider fuel system.
Engine cranking did you visually check for spark at the spark plugs? Engine cranking is there a fuel injector pulse?https://s8.postimg.org/50arofh11/fuel_pump.jpg
Click on the link for fuel pump relay, you can check the fuse. At the fuel pump, gray wire is voltage, black is ground.

WON'T START ENGINE JUST TURN OVER JUST CHANGE SPARK PLUG ROTOR DISTRIBUTOR CAP / SPARK WIRES


My first guss would be a fuel pump, just would have to verify that when you first turn on the ignition to crank you can either hear the fuel pump turn on in the tank or not, if you cannot hear the buzz or whine noise from the pump in the tank you need a fuel pump. Fuel pumps are a very common problem with these trucks.

Hard to start any time of the day for 1994 Nissan Quest XE.


turn your key on, DO NOT TOUCH THE GAS PEDAL and start, good luck. Pumping the pedal doesn't do a thing for fuel injection. In thre days of carburetors and you had control of your own property, Pumping did a couple of things. It set the choke and added more fuel. But that was yesterday and yesterday's gone.

84 toyota supra 5 speed man.


sounds like ecm. car starts but when it switches over to run setting from cranking setting the cumputer ecu doent activate the run curcuits which may control your fuel injectors. check to see if engine has spark. remove one plug wire from spark plug put it close to the valve cover if you see an arc then you know that you have spark. then also go to fuel pump in tank and check voltage on the power wire if you have good voltage and the pump doesnt make any noise while ur cranking then it may be a fuel pump if the pump is making way to much noise then check the fuel pressure by hooking up a fuel pressure gauge. all test are to be done while someone cranks the engine. noid light for the injectors, disconnect on injector electical connetor connect the noid light to the wire that u just unplugged from the injector. the light will flash while u crank , once it goes to the run circut the light will either stay on which will shut off ur car or the light will stay off which will do the same. if the noid light did what I said when it went to the run circut then it is what controls your injectors...ecm good luck....daniel
