Check the crank position sensor and all fuses and relays try swaping them around if they are they same part numbers, you can check the fuel pump for power and ground and check for these at the fuel pump relay also, do check the coil for power and ground also please rate -jeff

Gas Guage bouncing strong gas smell before 1998 Chevy Blazer wouldn't start at all. Engine still turns over


Check your fuel pressure, if low or no pressure, replace fuel filter first. My guess is the fuel pump and sensor are bad. You may also want to see if your getting spark, but I don't think bad plugs would make has gage jump around, but if they are not sparking correctly they will allow gas to flood the motor and that's when you get the gas smell

I have a 2001 Mazda Tribute, it tries to start but will not. How do I go about diagnostics on it?


With key on, check that all warning lights and the check engine light are illuminated. Also that the fuel pump turns on for 2 seconds. You should hear a buzz or hum from the gas tank for that 2 seconds with key turned to on. If the pump is working, that means gas should be to the engine. It may be necessary to check the fuel pressure. Some parts stores loan or rent fuel pressure gauges. If fuel pressure is correct, or if you are sure the pump is putting gas up to the injector's fuel rail, then check for spark on a spark plug wire while a helper cranks the engine over.

Gas and spark, that is what you test for first. You will also need to check for trouble codes with a scan tool. Parts stores will do a scan for free. But if it won't start, that may be a problem getting to a store. So it is gas and spark. If you have both, next would be to check the injector circuit. Answer back if you need help with the circuit. All you need is a voltmeter or a test light.

Car wont start


could be few different problems first u need to check for fuel pressure and spark
hook a fuel pressure gauge up and see if ur getting any fuel pressure if you have no fuel pressure u either have bad pump or out of gas (don't laugh i had cars come in shop for a no start that where just out gas)
if u have fuel pressure
then check for spark
take one spark plug wire of a spark plug and hold wire about 1/4 inch away from either the spark plug or engine block if u see a spark or hear one
if you have no spark your looking at a few different possibles Bad coil, ignition module, crank sensor, etc
if you have fuel pressure and spark but still no start u need to check for injector pluse (basically computer telling fuel injectors to open)
but now i think I'm getting over your head let me know if this helps and i try to walk u threw other things if this dont help

1996 Sonoma Problem


Not sure. You need to do a little checking of ignition and fuel delivery. I would first check for spark at all four cylinders to eliminate or verify if ignition is causing it. If you have distributorless ignition, you have 2 coils. One coil serves cylinder 1 and 4, the other coil serves cylinders 2 and 3. If for instance, you have weak or no spark on 1 and 4, suspect the coil for them.
If you have good spark on all four, a bright blue, snapping spark, then pull the spark plugs to check they are not fouled, like oil fouled that prevents spark..
If ignition is good, look to the fuel system.
Maybe an injector is blocked open by debris and won't close. That's very rare, but a possibility. The spark plug for that cylinder would likely be much wetter than the other plugs after cranking it over. Maybe the fuel pressure regulator has failed. If you can find the fpr on top of engine (some are located under the intake manifold, hard to get to. and some are fitted to the pump in the gas tank-impossible to inspect) then pull off the vacuum line to it and check for evidence of gas there-a sure sign of a ruptured regulator, and it will let extra gas get sucked into the engine-just like your problem. If you can't find the pressure regulator, you should have the fuel pressure tested-mainly to see if it is too high-also a pressure regulator problem,. likely.
IDK, maybe this will help you a little, good luck.

Toyota 4runner sr5 won't start its getting gas and spark.


Sounds like the problem is beyond your ability to diagnose

Too much fuel could be a leaking fuel injector or fuel pressure
regulator.

Too much gas & a no start isn't really the issue

Did it start & run before you did the wires,I would check your work
& mark the wires with a pen & also have diagram on paper before
you start a job like that. Especially when if you have no reference
material.

You put a mechanical fuel pressure gauge on a running engine
& the apply vacuum with a hand pump to regulator to watch for
pressure change,eg: pump pressure vs: regulator press

1992 Ford Ranger will turn over but will not start


Do you have spark? If you have spark then that probably means you are not getting gas. Try checking your fuel pressure. If you have low or no fuel pressure your pick-up will not start and means you probably have a bad fuel pump. If you have good fuel pressure then it is most likely your fuel injector. I hope this helps you at.

I put new spark plugs in and new air filter unclogged my cadalac converter yet im still getting 200 miles on a full tank of gas what could be the problem?


distributor cap, distributor rotor, spark plug cables, these can cause a spark to be to weak, which would cause the car to use more gas than necessary. fuel filter would also cause lower fuel pressure which would cause the car to use the gas inefficiently. tire pressure, if under inflated will cause to the car to push a little bit harder which could cost you a couple of miles to the galon. these are the only things i can think of that affect gas. other than that it would be something would have to be replaced like your o2 sensors. hope this helps, goodluck

Looks like gas does not make it to injectors. will crank but would not start like it does not get enough gas.


check the fuel pressure with a pressure guage, you also have to check for injector pulse and spark.
