Question about 1998 Isuzu Trooper

1 Answer

No start but cranks, where should I check has fuel and compression, no spark?

Getting fuel and has good compression no spark from plugs. Could all coil overs be bad? Could it be bad crank sensor or bad alternator?

Coil on plugs? not that. Crank sensor? could be, but check the wires also. They break close to the plug.

What do I need to do it is spin over but will not crank


Make sure fuel is reaching the engine as a first step. Have someone check the TDC crank sensor for you.

My car cranks but will not start RVR GDI mitsubishi


Check all fuses first, then with an assistant, check for spark with a spark tester. if there is spark at 2 plugs, check for fuel pressure at the fuel rail with a gauge. Engines need three things to run, fuel, spark, and compression. If there is spark and fuel, do a compression test, if the timing belt jumped/broke, you won't have any

If it cranks good but won't start, and it doesn't make any horrible noises when cranking, like internal engine issues, have a helper crank it while you visually check for spark at the spark plugs. If you have spark everywhere, use a gage and check fuel pressure.

Yes, valve timing could be an issue? Do you have good cylinder compression? Use a compression gage to check. Usually if no compression, the cranking rpms can be faster than normal.

Wont start


You need to check three things if your car wont start.check the fuel make sure your getting fuel to your engine.If so check to see if you have spark u can do that by taking a spark plug wire off the plug and put a screw driver in it have someone crank your engine and tap the metal part of screwdriver to metal if it sparks your good.the last is compression u need a compression tester to check that.

Car wont start or fire even with starting fluid


To review - - if you have spark, fuel, and compression, you should have combustion.
In this case, if the timing belt is damaged, you might not have compression or spark at the right time.
A faulty crank or cam sensor could cause you not to have spark at the right time.
The spark plugs could be worn out or fuel fouled and not able to fire under compression.
Did the car die or just not start ?

I have a 2003 Chevy cavalier that will not start or even try. It cranks fine, I have verified it has spark, I replaced the plugs and crank shaft position sensor, timing chain is intact, but I didn't...


you may need to check the compression. if the plugs have fuel on them and you know the spark is good then the only thing missing for the car to run is the compression. if all the cylinders have low compression then the car has jumped time most likely.

I have a 2003 civic Honda .engine cranking but wont start.Fuel and Ignition were check already no problem was found. Is it maybe because I have change the original alarm of my car to a new alarm? Do I need...


I would check your firing order, and all the stuff with the distributor, no loose connections and stuff, check the condition of all your plugs, make sure they are gapped correctly, check everything, maybe your injectors are clogged or broken? (unlikely but still check it out) then at last check for compression. All you need is fuel, spark and compression to fire. Check all cylinders to make sure they are ok on everything.

Get your tools (for removing a spark plug) ready. Try to start the engine, pumping the accelerator a little while you crank. Take a spark plug out. Is the spark plug wet with gas (smell fuel)? If so, you are getting fuel. Hook the spark plug you just took out up to the coil, lay it on the engine where it will be grounded to the metal. Get someone to crank the engine, and check for spark at the end of the plug. If there is a good spark, that eliminates another problem (don't crank the engine, or let it run too long with the plug out). If you have spark, and fuel, either the timing is way off (broken, slipped timing belt/chain), or you have no compression (internal engine).

Do you have a "Check Engine" light, or any other warning light on? Recently you make any work there or disconnected the battery? Are you thniking in Theft, Immobilizer or Passlock security alarm? Is this occurrs and the keys isn't work, its need to re-programmed, for this need to visit your Honda dealer.

Keep us updated.

"Cranks, but won't start". Replaced fuel pump, CKP, ICM & nothing


If the engine cranks over normally when you attempt to start you car, but the engine does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION. The engine needs adequate fuel pressure, a properly timed spark and normal compression to start.


1) To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. If it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.

2)Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.

3)Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine..

It cranks really good sputters a little and makes some loud pops but it will not turn over? FYI:Cranking and turning over are the same thing. When was the last time it ran. The gas could be bad. Did you get new plug wires as well. Try testing the distributor, remove a spark plug, plug it back into the wire, and touch the threads to ground and crank the engine. It should spark. Keep your fingers away, that's high voltage. Remove all spark plugs, spray some starting fluid in each cylinder, then crank the engine with the plugs out. This will clean any debris from the cylinders. Engines need backpressure to run properly, a major exhaust leak hence the popping, could cause it to not run. If you can get it started try to keep it going, full throttle, keep in the starting fluid, it could just need to get warm. I used to have one of them and they don't like it when they're cold.
