The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

Engine will crank but want start why? 1989 nissan pickup 4 cylinder the engine will crank but want start what all i need to check to fix this problem?


Check for spark at a couple of plugs and if you have spark spray some carb cleaner in the throttle body to see if she will run .

95 Buick Regal will not crank when engine warm wait 20 or so minutes and it will crank what causes this issue.?


Define crank ? Does the engine spin when you turn the key to the start position ? This is referred to as engine cranks . now yours won't start an run ! This is a cranks no start condition ! When it won't start an run check for spark at a coil , your vehicle has three if a V-6 . Pull both plug wires off same coil an crank engine , is there spark ? Yes - No . No spark , ignition module could be bad , crankshaft position sensor , Your best bet would be to take your vehicle to a qualified repair shop .

Engine turns over but won't start


Start with testing the coil. Disconnect the wire and have someone crank the engine to check for spark. The spark should jump about 1/4 inch. If spark is good, suspect fuel problem. Spray some ether into the intake while the engine is cranked. If it starts and then stops, it is a fuel problem. Your battery is probably going to go dead with all this cranking, so keep a charger on it. Also give your starter time to cool between long cranking.

How to check a ignition coil pack to see if its good,


the coil does not crank the engine , the starter does that, sorry.
(if you ever had to hand or foot crank and engine , youd under stand that. (like motor cycles or boat engines, or per 30s cars.)

in fact will crank all day with no spark parts on car..

x2, the scan tool does tell you why there is NO STARTS, CRANKS OK. The pcm can detect, one missfire in 10 cmp;ckp signals.
  • CRANK FOR 5 SECONDS
  • release, key
  • scan tool has DTC errors?, read the believe them.
no engine stated of 4 or more,

U checked everything but spark,
why, check spark at all cylinders, all most fire or the engine will not run or stall.
That test be first, if not starting (AFTER SCAN TEST)

IF NO spark fuses are next , not last.
lets do no start fails tests. (cranks perfectly 200 to 300 rpm)
  1. : check fuses
  2. key on, CEL lamp must glow, if not , ECU fuse blown.
  3. crank with scan tool , see P03xx DTC errors, see RPM dead.?
  4. check for spark? got spark x4 or times number of cylinders?
  5. got spark try test fuel now, runs for 3 seconds?
  6. yes, runs on test fuel now means lost fueling
  7. no, dont run on test fuel, means, 1 to 5 done wrong above or engine compression bad.
  8. bad fueling, huge number of tests. check fuel pressure now.
confused, try a shop and watch them, learn.

NEW BATTERY, NEW ALTERNATOR, ENGINE WILL CRANK BUT NO FIRE.


no engine option size stated, so i wing it..(generic is harder)
ok battery changed, no need for jumper cables now.
engine cranks robustly.
so no fire, i hate to tell you that word means (NOTHING)
there is fire to each spark plug (tip spark = fire) then there
is combustion fire , a goal on all cylinders.
so use the word spark , you then check spark at all cylinders.
please.
if spark is gone on 1 cylinder work that.
if spark is gone on all cylinder we then scan the ECU.
RULE 1, no EFI car , runs fueling unit (IT) thinks(sic) there is spark (3 way checks) this is Crash and fire protection on call cars.
most books fail to say this very important feature in all modern cars.
so that is why spark is 1st. never ever done last.
you crank engine for 5 seconds.
release key, not off. the key yet.
and the scan tool, shows P0340/355 or any codes relate to spark
CMP./CKP ,etc.
and the rpm shows 250RPM cranking, yes,the scan tool can see
RPM cranking and is a TOP check , missed by many noobs.

so now you have spark
on all cylinders.
we cross fingers #1 is good, 150PSI compression on all cylinders, min.
and blame fueling.
A: is it flooding or starving???? the spark tips (i bet its tunedup, huh)
are dry or wet.
B: more later if you get this far.

just oneline says it. for 100 years now. (otto cycle engines)
(cranks ok, compression good,spark good x4,x6, fueling last)

Cranks won't start


First you must check to see if engine is mechanical sound by performing a compression test. remove the spark plugs install a compression gauge in the spark plug hole and crank engine about 4 cycles compare readings to all cylinders reading should be around 125-150 psi readings in the 50 psi range possible jumped or broken timing belt. If engine is mechanically sound test for spark at the spark plugs use a spark plug laid against valve cover and have some one crank it over look for the spark to jump the gap. A no spark problem is internal in the distributor.

No spark


Yes. No crank sensor signal usually means no spark. The ecu has to receive crank position to set spark timing. I think you've really hit a big problem. You may need to get in touch with some people who have done this mod. I've always heard it's best and easiest to swap the engine with its ecu and the wiring harness into another car. Or something more compatible with that jdm engine.

Cranks but wont start


Engine Cranks But Will Not Start

For an engine to run, you need three things to happen inside the engine. Compression, fuel and ignition, without any one of these components the engine will not run.
Basic Checks:

A. Test Fuses. Test both under hood power distribution center and the fuse panel under dash. This is done with a test light tool. The test light should illuminate on both sides of the fuse, if not the fuse has failed and needs to be replaced.
B. Testing Fuel Pressure Test for proper fuel pressure with a test gauge on the fuel rail, most throttle body injection cars (TBI) are between 13 psi and 17 psi. and most (DPI) direct port inject systems are between 40 psi and 55 psi. If no or little fuel pressure is observed and there is 12 volt power present the fuel pump, the fuel pump needs replacing.
C. Checking Timing Belt Test for compression by removing a spark plug and insert a compression gauge. Crank the engine over about 5 seconds the gauge should read between 125 psi and 165 psi, if no compression is observed remove front engine cover to inspect timing belt or chain. Crank engine to observe cam rotation, if the cam does not rotate the timing belt or chain has failed. (note: if the timing belt drives the water pump it is best to replace the water pump at this time)
D. Test for Injector Pulse Remove injector connector to insert injector test light (node) or volt meter. Observe light flash or gauge pulse while cranking. If light/voltmeter doesn't respond, an ignition distributor/crank angle sensor (CKS) or an ignition module is most likely your problem.
E. Test for Ignition Spark Remove spark plug wire, insert an extra spark plug into end of wire, rest spark plug next to a ground source then crank engine. You should observe a blue spark between the spark plug gap and ground source. If no spark is observed, an ignition coil, ignition rotor or spark plug wires might have failed. (always keep hands away from engine when cranking)
