I was driving my 1994 isuzu rodeo and lost complete power.Got a few jumps and truck wont start.sounds like it wants to start when i turn key over.I also put gas in and still nothing


run the fault codes
check for cam/crank position sensors failure, immobilizer failure , pump operation
could be a failed ECM
have the battery load tested as it may be the original fault and jump starting may have caused a power surge and damaged the ECM

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

I have a 95 grand Cherokee. I'm getting fuel, and I'm getting spark. I replaced the crankshaft position sensor, and it still wont start. I spray starting fluid in carb, it starts and dies. Please help


what does getting mean? which engine, 4Liter or 5.2 or what?
spark at all cylinders is getting and timed right?
runs on test fuel so sparks good, that means fuel is bad
or flooding or too little fuel.
code 12 cranking for 5 seconds, means sensors are ok.
why replace parts that make spark when sparks good, it run on test fuel, why worry spark.? and not just fueling.?

now lets do fuel, step one is fuel pressure, not squirt tests.or dribble test. a real tool called,a fuel pressure gauge that works, and nothing else, (unless rail is dry and now we know its not)

if all spark plug tips are dry, are they?
then its not injecting, (the ECU can cut injection for 2 reasons) ask
or there is no real pressure.
so we open the FSM and read page FUELING
49psi is idle pressure, (more cranking with so little vacuum)

the tests are all there,

Where is the fuel pump located on a isuzu v6 holden jackaroo motor 1993 petrol


the usual place to think of would be inside the fuel tank. when thy went to electrical fuel pumps from mechanical that is where they put them .could be a bad relay or even as simple a thing as a bad ground

Car won't start once in a while, mostly after it sit's a few days. it cranks ok and almost starts. good spark, and has fuel but I can't test fuel pre. if I pull the lines from the tank it starts and runs...


your on the right track,you need three things to run an engine spark fuel and air,you can test your pump another way its primitive take 2+2 carb cleaner get access to your throttle body have someone try starting the engine while another sprays the carburetor cleaner into the throttle body if it runs while you spray and then stops when you dont your fuel pump is the problem.Chrysler is know for this fuel pump problem.

96 bravada replaced fuel still no start runs with starter fluid


If your getting gas and spark get an obd 2 scan tool and check your mass air flow sensor. I had the same problem. If your having a problem with this vehicle always check the computer first; it will save you tons of headaches later.

No power to fuel pump, relay is good, engine cranks over but won't start.


You need to follow a detailed troubleshooting procedure in a repair manual.
Check for spark plug fire during cranking after it dies.
No spark = ignition problem= computer will not fire injectors, and possibly cut out pump also.
Good spark = pump wonky, or power to pump system.
Also, other quick tests... when the thing dies, and then you crank,
1) Thump the fuel pump in the tank, if you can. A bad fuel pump might start up again.
2) Shoot some ether carb cleaner in the TB. If it only fires off the ether, the ignition system is no longer suspect.
