Sounds like a fuel pump. You can have your SUV hooked up to a fuel system pressure gauge and see if you are getting 36psi or higher. Anything under that and you have a bad pump.

Changed coil packs and still misses


With the car running take a can of starting fluid and spray around the intake. those cars are known for bad intake gasket leaks. if the engine idles up on its own when you spray it. you have a bad intake. make sure to check and spray vac lines as well.

Chrysler pacficia wont start when i turn off car and i just got a new starter?


get some starting fluid and spray it in the throttle body and if it starts and then dies you lost fuel and it can be as simple as replacing the fuel filter and adding fuel injector cleaner but if it doesnt start then u lost spark and just about all the time on vehicles with coil on packs its the crankshaft postion sensor

Mazda RX 8 was running parked it overnight and will not run. Change the coil pack and spark plugs. It still will not start. If you think it could be the fuel filter tell me where its at or any other info...


I would like you to verify spark. You can get a spark tester from a local part store for less than $10. Just pull the coil off of a spark plug, put the tester in the coil, ground the coil with the clip to a clean metal surface (preferably the block), and have someone try to start the engine. Only turn the key long enough to see if you have spark at the tester, shouldn't be more than a few seconds. If you have spark, put the coil back on the plug in the engine, spray some starting fluid in the air intake and see if the engine tries to start on the fluid. If it does, then we can be mostly certain you have a fuel issue. Let me know the results of the test. You can try spraying the starting fluid before you do the spark test. If the engine doesn't try to start on the fluid, then you need to do the spark test.

I'm helping a friend to get his 02 Ford Explorer going after sitting for about 6 months, put in new battery and checked fluids then tried starting. it would crank over but not fire up,tried numerous times...


You need fuel, air, and spark to start it. Make sure the engine is getting fuel. Make sure the pump is working. Fuel goes from the pump to the filter, through the lines, to the engine. If the engine is getting gas, you need to check for spark. This concerns the spark plugs/coils, wires, distributor, coil pack, dist.cap, rotor, cam sensor, crank sensor, timing belt, ecm. It is a lot of things but anyone of them can make the car not start. That is why it is important to do a fuel check and a spark check. If it gets fuel, that cancels out fuel. Same for the ignition system, where you get the spark. If you have any questions, just let me know.

Truck wont start has power just click click


The starter and starter solenoid has to be checked.There are few more possibilities that also are to be checked to confirm the fault.But as per click click its indicating faulty or loose connected starter or jammed starter solenoid.In both case the starter assembly has to be replaced. The other possibilities as follows:---

A car that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also these problems are related to faulty spark plug. Check the spark at spark plugs when you start the car. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt. If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced. If all the possible options checked out ok then check the car starter. The starter gets power from battery to start the car. If the starter is faulty then it will not let the car to start. Also check and confirm that there is fuel in the car. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the car. If the car starts momentarily, then there's a good chance the fuel pump is not working or the car is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks. Helpmech.

2.8 engine Would start when cool, but stall after


89 cierra? It should be DIS ignition so you can't have the timing too high. You said it has fuel and spark. Fuel pressure and injection pulse. Does it try to start if you spray carb cleaner into it?
