When you have an engine that is hard to start or the engine takes longer than normal to start, with a fuel injected engine it will normally be caused by a fuel problem. Another problem would be slow cranking of the engine because of a low battery, I would check all of the fuel related problems if the engine seems to crank normally. There are a few things to check. First pull the fuel filter off and wipe it off so you don't get gas in your mouth and try to blow through one of the fuel connections on the filter. If you can't blow through it the filter is pluged and needs to be replaced. A plugged fuel filter can cause hard starting and can also damage your fuel pump. The next thing to do when everything is put back on the car is to check the fuel system for bleed down. You need to locate the fuel pressure test connection on the engine. Connect a fuel pressure gauge to the connection and start the engine, then turn the ignition off. With the engine off the pressure should read and stay between 30psi and 40psi, to be sure of the pressure you will have get the spec's on the engine you have. The main thing you will be looking for is to make sure the pressure doesn't start bleeding down in to direction of zero after a few minutes or maybe even immediately. If you see the pressure start to bleed down you have a problem. There are two problems that normally cause the pressure to bleed down. One is a bad check valve in the fuel pump, the other is a bad fuel pressure regulator. The main thing that happens with a fuel pressure regulator is the diaphram inside starts leaking. When that happens sometimes it will leak fuel into the intake manifold through the vaccuum hose connection to the intake manifold. To check for a fuel leak through the vacuum hose connection, locate the vacuum hose on the fuel pressure regulator and pull the hose from either the manifold connection or from the connection at the fuel reguator. If you see any gas at all the fuel regulator is leaking and must be replaced. If it is a slow leak from the regulator you might have to start the engine with the vacuum hose disconnected and look for a leak from the hose. If you don't find anything wrong with the regulator the next problem area would be fuel pressure bleeding back into the gas tank because of a bad check valve in the fuel pump. If this is the problem the fuel pump would have to be replaced. My first guess as to what is causing your problem would be the fuel pressure regualtor although I would definately want to make sure the fuel filter is not plugged. (Please Note) The fuel pressure regulator is located in the intake manifold area of the engine. The fuel pump is located in the gas tank. The fuel filter is located usually somewhere under the car.

Why won't our pilot start?


When you say a car won't turn over, that generally means it will not crank. You said it tries so I assume you mean it cranks and doesn't start. If that is the case, you could have a problem with fuel delivery or spark. It will take some good ole fashioned troubleshooting to prove or eliminate these items. Once you do, you will need to find out why you don't have what you need. For example, I have no fuel getting to my engine. There could be more than one reason for this. Electrical, mechanical. Maybe you have fuel but, no spark. You will then have to find out why. Can you check any of these items?

The BCM has nothing to do with the starting of the vehicle . ( lately it doesnt start ) ?????? Doesn't start how ? When you turn the key to start does the starter spin the engine ? But doesn't start an run ? This is a crank no start condition . Sounds like a fuel delivery problem , what is the fuel pressure ? What engine ! What type fuel injection ( CPI ) Try spraying carb cleaner into the engine ,through the throttle plate an see if it starts then . fuel pressure should be 415-455 kPa (60-66 psi)

1990 Nissan Stanz. We just purchased this car for our son as a first car (bought it at an aution) The car is getting oil pressure and fuel to the engine. Problem it turns over but will not start. We tested...


you should chek ur actual injector pulse to see if fuel is gettn injected into ur engine. one way to see if its a fuel problem is to try shootrin carb cleaner into ur throttle body or a vacuum hose directly on the intake manifold while cranking engine an even see if it try to start. if it pops over an trys to start then ur spark is obviously good enough,an ur not gettn injector pulse. all ur injectors should have 12volts and only the ground gets pulsed on and off to open an close injectors,while someone is crankin engine.thats wen voltaged needs checked. if it trys to start then i woul def check ur cam sensor which controls injectr pulse ,most likely located in ur distributor.also good idea to chek all ur fuses,and even try to see if there are any codes in ur computer system,which their probably are. very important wen diagnosing a no start condition. good luck coutybgg

What are the symptoms of a leaky intake gasket?


most common symptom is a misfire, however a good test is to spray brake cleaner around the intake mounting area while the engine is runing. if the engine trys to die, or the exhaust starts to stink you have a leak

Driving home, 2003 Dodge neon starts to slow down, oil light has come on intermittedenly before, engine started to lose power, brakes locked up, and steering wheel locked up. Car had to be towed. Thanks.


lets hope its not a bad motor from lack of oil pressure, the loss of brakes and steering is due to the engine stopped running this is normal, but hte oil light coming on with the engine running is not good, you will need to see if the engine spins and trys to start, this will tell you a little bit, if it spins then it didnt lock up, and maybe its a fuelpump or timing belt that let go, you will have to do some testing ,check for fuel pressure and spark at the plugs,

My van won't start. The serpintine belt broke and I replaced it. It is installed correctly but the engine won't turn over. It trys to start but won't. Any suggestions?


How long did you run the engine after the belt broke? Does it sound like dead battery? The alternator quit when the belt broke, the car will run for maybe 20 mins without it, I would say you wore down the battery, get it charged back up and see what happens. There is nothing else that will make your car not start that is attached to the serpentine belt.

My Kia Sorento won't gear down and accelerate when I floor it. Dealer says it's a sensor in the transmission and they need to drop the transmission ($400 labor) to replace the sensor. I have a feeling that...


TPS of Throttle Position Sensor needed adjusting and is the problem and not the gearbox.

This usually happens when the engine light comes on and the TPS is adjusted but most dealers forget (or maybe intentionally) to reset the gearbox P/TRN Fuse.

Whenever the engine light comes on the gearbox is set to run in Sick Slow mode which is why you have this problem.

Before doing anything, try pulling the P/TRN fuse for 5 mins and put it back. Then try the car.

Hope it works, i did for me.

Won't start after sitting for 6-8 months


First,try to get engine to fire and eliminate the ignition as the problem.While cranking squirt start fluid into intake and see if engine trys to start if it does you will probably need to fix the fuel system as sitting for that long will ruin it due to stale fuel turning corrosive.Pump filter etc and injector cleaner to try to clear gummed up injectors.
