May be an ignition problem, you will need to get a wiring diagram, in this case I would suggest a Haynes/Chilton manual for your vehicle that can be purchased at any auto repair store. You can also try the library, Good Luck Tim

1988 2.5E s10 no fuel


you mean,cranks ok, but will not start and no fuel , right>?
s10 no fuel. 1988 ( S10 blazer )
please do say , what that means.
1: car cranks and will not start. so must be out of fuel?
(over 50 causes, or better is 10 or less tests (ask)
2: same, and fuel pressure is 0 psi (spec.9-13). gauged.?
3: fuel dribble test?
4: sparks good so tired test fuel and it ran on test fuel ok? proving
loss of fueling>?
5: injector dead cranking, (eyeballs)

which was it?

1988 cars in the USA are BIG TIME TRANSITION year.
we went from CARBS to EFI.
2.5L (what is E)?
gear cam, roller HLA lifters.
your car, USA , is TBI engine,
TBI started on THIS car in 1985 (1/2 and 1/2)
Throttle body injection
an on all TBI engines, one can see it inject with eyes.
does it?
if not it can be the following things.
1: no fuel pressure, 9-13pis.
2: ECU is cutting fuel. Pressure good cranking.
2a: ECU is sending error for bad crank/cam sensors, and cuts fuel.
2b: ECU sees rpm or tacho line dead.
2c. ECU sees TPS sensor output as 4v or more cranking, this cuts all fuel.
3: if ECU is happy, it sends 12vcd to the pump, cranking.
all tests must be dont cranking or chase tail.

Why is my 04 liberty jeep 3.7 injector number 1 spraying fuel once ignition is in (on) position


Sounds like the relay is stuck in an open position and needs to be replaced.

Ok guys I have a 97 lhs the fuel pump went bad replaced it car ran great again but now it wont start turns over have replaced the fuel filter and the coil pack and still it wont start im stumped please...


this is not unique to chrysler, at all, its EFI.
all EFI works alike , the shapes change to fool the non tech.

i dont know about you, but in my shop
i check fuel pressure and you found it at zero
then put in a new pump and didnt check pressure.
why would you do that? after all it was zero.
and you do that and its still zero. then find a bad wire /connector
in the fuel pump power feed or the fuel pump relay.
or ? a inertial cut out sw, or rollover switch. (i said generic)
now rule 2: if spark is bad, the ECU cuts fuel,
BY DESIGN. that dont mean spark really is bad, but does mean
the ECU can not SEE spark, or that the Tachmeter line is dead.
All ECU monitor spark 1 way or the other, and if that fails.
there WILL BE NO INJECTION period.
use your scan too to see DTCs while cranking and dead RPM cranking for 5 seconds, release key and look for crank or cam
sensors errors, key key on for 1min to see them pop up.

your are stumped because you are not troubleshooting, only guessing. and will make you broke fast.
here at the simple tests, in the proper order.
1: compression on all cylinders. if all are horrid.
the cam timing is way off. no motor will run like this.
2: spark check for spark. ! at all spark plugs, not just one.
3: make sure the ECU is happy about spark, RPM moves cranking , etc.
if spark tips are dry at this moment test fuel can be used.
does it start now then stall as the the test fuel is consumed.?
4: check for injection.
do the injectors click , do all of then click , cranking>?
if all fail, i can assure you the ECU is CUTTING FUEL!!!
if one dont click , then run a NOID lamp test in this injector
and make sure the coil reads near 10 ohms not infinity.
5b: you can do an injector balance test.
cranking, see that the pressure drops, as you crank.
Ill not cover this , as its a SOP proc, in all EFI books published.
but take to bank, can witness the drop in pressure and know the injector does in fact inject.
that way or by looking at fuel soaked spark tips.

the injectors can fail in many a way, they are fuel cooled.
A:shorted coil, open coil
B: ecu driver dead.
C: injector clogged or leaking (leaking causes flooding)
the injector has inside 10 micron screens. tiny,
d: bad fuel. cant burn or clog s screens.

you are now totally confused (above) or are un-stumped.

if you dont understand EFI at all , then lets go back to 1920.
this works too, on all otto cycle engines
1: compression, good, time number of cyclinders.
at spec. all equal, most 150psi to 200 is typical today.
2: got spark times all cycliners.(oh, yes, timing right)
3: over fueling or under.?

that is it, its and air pump , if it can pump air, it's hopeless.

the 3 steps work , every time. the tests are easy and are documented for 90 years, now.

It just clicks and won't start


Hi there:
You will have to pinpoint what the engine is missing... Spark / Fuel / Compression

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.

Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

2005 expedition 5.4 bank 1 too rich, cylinder 1 misfire, o2 sensor 1 error, I changed o2 sensor,spark plug & coil but engine is still smoking,raw fuel, doesn't seem to be firing on bank 1


un plug the fuel injector and see if the raw fuel smell, goes way, if it does the injector could be stuck open. if this is the case the more you run it the more fuel is getting into the crank case, this can wash the bearings and ruin the engine, check the oil see if you smell fuel if you do, you will have to pull up the injector rail with all the injectors and cycle the key one time, watch that injector to see if it drips fuel after the rest have stopped . if it leaks replace the injector all the injector o rings and change the oil.

I have a 98 blazer.The fuel pump is good and filter is new.Im getting gas to the fuel lines-but something is stopping my fuel injector from cutting on!! When I pour gas in the throttle body it starts up...


check to see if your getting a pulse on the injectors
if it has the spider injector with a fuel pressure gauge check pressure see if it drops or have 55 to 66 psi check to see if also check the eng 1 fuse cgeck ecm 1 15amp

Having problems with my 1998 Saab 900 se turbo, the car would not start i thought it was due to the cold so I put the car in the garage next day the car started the next day the car started, Drove it and...


Based on the information you have provided your problem is one of two things
1.Bad fuel pump -to check this have the fuel pressure tested if above 40psi you should be able to start the vehicle. (you can borrow/rent a fuel pressure tester at an auto parts store)
2.Bad crank and cam sensors -these are what tell the injectors to fire, so if you have good fuel pressure to the injectors but still no start I would replace both the crank and cam sensors.
