If its a manuel trans it could have a bad clutch switch.an automatic trans could have a bad nuetral safety switch. both can also be just out of adjustment also.its also possible the ignition switch is bad or out of adjusment by loose mount screws or brohen switch linkage.try this MAKE SURE ATOUTRANS IN PARK AND WHEELS CHOCKED BRAKES SET,SAME GOES FOR MAN. TRANS.. the starter relay also called solonoid on fords is on the inner fender near battery. there are two large cables, one to the battery other to starter. there are two smaller terminals inbetween the two lare ones. turn the key to on, take a jumper wire and touch the stud that has the cable that goes to battery positive then touch the other end [while its still touching the pos cable] to the smasll terminal that is closest to the battery pos,there right next to each other. dont worry if somehow you touch the wrong little terminal it wont hurt anything it just wont crank.if it turns over then your problem will be one of the above mentioned possibiltys.

Why won't 89 Chevy Silverado 1500 5.7 STILL not start. New battery,coil,spark plugs,wires,inline filter,distributor,cap,rotor,fuel pump,starter relay.


What's missing ? Fuel ,spark , compression ? How many miles on the vehicle ? Does it have spark , pull a plug wire while cranking an hold it near a good ground . Put a fuel pressure gauge on the vehicle , is there fuel pressure ? Do a compression test , 150 psi . engine mechanical problem . timing chain .

My 89 Chevy Suburban Silverado STILL won't start! New coil, spark plugs, rotor, cap, relay,battery,inline fuel filter, fuel pump,solenoid.


Have you checked for spark at the plugs ? Spray some carb cleaner into the throttle body and see if it attempts to run as this can show a fuel problem .

Where is fuel pump fuse


4.0L engine inline 6, ? must i guess that? EFI varies by that.

its in the fuse box? i bet you want fuse actual name....
ok, 89 is a very old car, sold all 2 of mine. early XJ jeeps. (AMC )
the 89s have this junk french ECU. called RENIX google this pos.
no scan tools fit it, is why i dont like it.
93 up are good jeeps.

my guess is , engine dont run, why not give full inputs to the tech.
like that. so i can be on same page.... yah think?
but ok, ill play this game.....
Easter egg hunts to nowhere.
normal fuel pressure is 31PSI.
if zero pressure we check 12vdc at pump cranking.
if zero volts at pump cranking. then check fuel pump relay.
all 4 pins, (ask for checks )


the fuel pump relay has 2 fuses. one is ignition fuse link F green
and the pump fuse is G orange.
the full schematic is at alldata.com anyone can look, pay fee.

of fuel pressure is ok and injector dont inject well that is a longer story, that i can answer easy, so ask.

Has power, fule pump is working, won't turn over?


? no engine stated of the many.
cranks, ok? fast and normal???? or weak....and slow, 250rpm is norm.
12vdc good to EFI ,ok (power sure)
spark is next. not fuel. ever. same for carbs to EFI.
check spark if spark is good, try test fuel if test fuel fails it flooded
or the engine has lost compression in 1 or more cylinders 4 to 6 ?
then if test fuel works<<<< we attack fueling. last.
fuel pressure at spec? using a real gauge not sounds. or dribbles.

you using turns over to mean starts and runs? lots of parts turn over.
Running is and end goal and full engine power.

The EFI will not inject fuel if it even suspect spark is bad.
so spark is 2x more important than carbs (logic in the ECU)
this is for fire safety.

my motto:
NO YEAR
NO MODEL
No engine. (or transmission type A/T or M/T?, if that is in question)
NO HELP (or your joy)

98 jeep put new crank sensor ' coil pickup' and coil ' i have no power to the fuse block on finder no fire to plugs and dont here fuel pump


No power to fuse block? This may be the problem. Check all your maxi fuses in the power distribution block. I think all the maxi fuses are hot at all times-check if they are getting power, and fuses are good.

Also in the power distribution center is fuse F15- a 30amp fuse for fuel pump relay, and fuse F6- a 15amp fuse, also for the fuel pump wiring. Check that both are good, and have power-F15 is hot at all times. F6 is hot in run or start.
This is the 4.0L inline 6, right? That is the engine diagram I have. The coil signal is from the ECU. Does the check engine light come on with key on, so you know the ECU is powered?

My 1991 toyota 4runner keeps blowing the efi fuse and my engine floods gas. what could be the problem?


Check the EFI main relay, the circuit opening relay, and the fuel pump relay. Inside the fuel pump relay there is a switch controlled by a coil. During start, the fuel pump gets full power for a couple of seconds to build up pressure. Once pressure is good, the fuel pump relay is supposed to switch (via the coil) the fuel pump to reduced power. If the coil in the relay is bad, the reduced power setting is not available and the fuel pump will run at full power all the time. At this heavy current draw, it won't be long until the EFI fuse blows. This would also give more pressure than is necessary to the cold start fuel injector which runs on a timer. This extra pressure during the time that the cold start injector is operating may be the reason the engine is flooding with fuel.

We have a 1987 stanz, new battery, aleranter and replace one relay switch and both fuel filters. It will start and run(not good) you can drive it a little while and it will run good a minute then blog down...


1987 Nissan Stanza

you will need a repair manual
http://www.nicoclub.com/service-manual?fsm=Stanza/Sanza_1989_FSM

comes up as having both efi or carby what has yours got

if carby its a lot easier to bypass the faults to get it to run

will assume its EFI

EFI will be a problem if any wires have shorted
may have blow the large fuses in the engine bay giving power to the car


for both carby and EFI
pull the light fuses and relays out

check all fuses and relays in the engine bay cluster are not popped

starter relay and EFI ecu fuse are in the engine bay cluster

if the motor turns over
the fuel pump must be pumping fuel with pressure required to run the car to get fuel to the carby /or fuel rail and injectors
if you get that
only have to worry about spark
have you got a good coil arc and spark to all plugs

The TFI module is on the side of the distributor but I would recommend replacing the module and stator witch is inside the distributor..... Have you checked to see if you have voltage to the coil?

I have a 94 cherokee coutry w/inline 6. When I


First place to look is in the wires from the battery to the starter and the battery to the ground... got corrosion? this can really choke off the flow of electricity to the vehicle... check both ends of the starter cable and the ground from battery to frame (or block or trans) any kind of green or white deposits indicate it's time for new ones... this can be tricky because the corrosion can be inside the insulation on the wires... if corrosion is bad enough even a jump won't start the vehicle as not enough voltage will reach the coil... if the wires are good then it's time to check the coil and it's wiring... if you aren't real savvy at testing components with a meter then replace the coil (assuming good wiring) and test for spark by holding coil wire about 1/4inch from the block or any good ground while turning engine... you should see a nice blue spark... hope this helps...;-)

89 f-150 turns over just wont start


If the only evidence of trying to start was when u used starter fluid, it's probably a fuel issue. After attempting to start several times, pull a plug and check for gas/wet plug. If there is no evidence of gas reaching the plug, it's probably the fuel pump. Change the fuel filter too.
