SOURCE: 1998 Chevrolet Cavalier sunroof will not open

if the roof is stucked up pull at the rubber lining around the inside of the sunroof (the one that seems like its just for looks) near the control button. then pull down on the inner roof cover and you'll see the back of the control button. there is an electrical connection there. see if it has come apart,. also check out if the motor of the roof control is spinning.if it is not spinning then replace the motor to make it work.

SOURCE: no spark 350 chevy tbi

You need power on both sides of the coil with key on engine off. With test light on neg side of coil you should get flashing light with engine cranking. No flashing indicates no trigger from ign module. No flashing can also mean the pick-up is faulty. To check pick-up dissconnect from module and use analoge meter set on ohms.Check meter movement during crank. If o/k check rotor for burn through.and change module.

I have a 1990 chev silverado that won't start has fuel pressure has spark injectors won't inject changed injectors could the throttle position sensor being bad cause the injectors not to work


No. If it is throttle body injectors(TBI), Check the plugs for power with the key on. No power, check fuse and wiring. If you have power, use a test light at the injector plug on both pins, crank the engine, the light should flash. No flashing, check the wire from the plug the the engine control module(ECM) If it is good(less than 5 ohms and not shorted) replace the ECM. TBI Has only one driver in the ECM, fires both injectors. Multi port injectors(MPI) has several drivers in the ECM. Unlikely they all died at the same time. Unless you have recently done some welding on the truck. Being it is a 90. I would pull all the fuses and visually inspect them. This also get rid of any corrosion problems. Fixed many problems by pulling a good fuse.

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.

90 chevy 350 tbi crank no start, truck was started driven around the block parked it and let it idle a few minutes before shuting it off, the next day it would not start, it acts like timing is off and is...


You first need to check the fuel pressure, an easy way to access this is to buy a can of spray starting fluid, spray it into the TBI throttle valve and if the truck starts and dies you have no fuel pressure. Replace the fuel; pump, and make sure you get the right pump, it is a low pressure system.

91 chevy cavalier 2.2 engine turns but that's all . ECM ,coil,fuel injecter,fuel filter, and intank fuel pump replaced 2 days ago.


OK FIRST PULL A WIRE OFF A PLUG CRANK ENGINE OVER AND CHECK FOR SPARK. THEN YOU ARE GOING TO HAVE TO CHECK FUEL PRESSURE. THIS HAS TO BE DONE WITH A GAUGE TO SEE IF YOU ARE HOLDING 9-13 PSI ONCE YOU FIND OUT WHICH ONE IS MISSING YOU CAN FIND THE PROBLEM. IF YOU HAVE BOTH IT IS TIMING . THIS VEH HAS A TIMING CHAIN. SO FIND OUT AND RE POST AND WE CAN HELP YOU GET THIS STARTED.

1990 full size blazer starts fine idles then dies


sounds real easy either a bad idle air control solenoid or more likley a blown throttle body gasket. to test fro a blown gasket, with engine running and cool spray carb cleaner or brake cleaner around base of tb were it bolts to intake. when it hits the bad area, should idle down and be normal for a second or 2. iac is possible,try this first since its so common and let me know
