Those injectors will not spray EVEN if they have the pulse going to them if the pressure is less than 20-22. It's got a new crank sensor, so what does that leave? Fuse/relay? (I've checked a few of those, all good) Fuel pump? PCM? So it's getting spark and must be a fuel problem.Īs you said, even though there's fuel at the rails, the injectors must not be firing. TobyU you genious you, your advice is terrific! I sprayed some starting fluid into the intake and the engine lit momentarily. They lose connection and no power goes to fuel pump relay. The 90-97 wasn't too bad for this but the 98-02 is terrible about corrosion on the large maxifuses on driver's inner wheelwell.

I think it's up in power dist center by batter bur could also be one in fuse panel above drivers knee.Ĭheck owner's manual or look up fuse pump location. There is a fuel pump fuse too that sends power to that relay. You could have good pump with no power being sent to it and same symptoms. You really want to check that fuel pump relay's terminals to MAKE SURE you have power going to pump and pump IS bad. Get under there and beat on bottom /side of tank and near top sending unit while someone turns hey on and off to see it is spins. If so you probably need fuel pump BUT those years are bulletproof!!! I bet it will start for a few secs if you give i a good spray of starting fluid, gas, and maybe carb cleaner. I'll try sqirting some carb cleaner next. If the pump is working you WILL KNOW it, as gas shoots up and splashes off hood.Īlright, so I got in the box and swapped the fuel pump relay for the a/c cutoff relay - still no startee. just push the needle on the valve on the fuel rail or even use tire gauge to press onto it, while some one turns on key. I think you will find an issue at the relay or at least find out that the pump is not spinning when it should. This is the first fuel pump diagnosis other than listening at rear seat for it to buss when someone turns on key. Then you jump it to the 87 term with needle nose pliers or a thick wire and see if pump runs in tank. You need to get to that fuel pump relay and see if the 30 terminal has 12 v from battery all the time. If you want to listed to radio you have the ACC position. No reason to ever have kep on with engine off. Just you did NOT want to leave key on with engine off because fuel pump was always running. LolĮnded up running a new wire from the key on position fuse box power to the fuel pump low voltage side. Then back to normal for miles then mess up again.įound the 12v from ignition switch was not getting to fuel pump relay low voltage energize side to kick on and maintain relay engagement.Įven swapped ECM and no change. It would barely power it and car would run but only super slow and low rpms but you could limp for blocks. I had a 92 that would get hot on hot days and cut out fuel pump. Have you used key on driver's door to lock and unlock it a couple of times to make sure it is not trying to go into theft mode. Is your theft light security working like it should and not flashing or going into theft mode?

If this pops you will get crank but no start just like a bad fuel pump.

HAVE you checked the fuel pump inertia safety cut off switch in trunk by driver side hinge? This means fuel pump, relay, switch or wire issue. If it is a fuel prob it will run for a bout 3 seconds each time you do this. Or you can hold open throttle plate and spray then let throttl eclose and get inside and crank. Spray some starting fluid or put some gas into a pump spray bottle and spray 4 pumps into while someone cranks engine. You need to pull the plastic snorkel off the engine that comes from air cleaner. You can get a much better idea where to look first. This is why I use noid light to see if there is pulse. Too bad the crank sensor wasn't the prob.

Usually a piece of tape around it but it has a little lift up clip on the sides. Newwave, haven't tried starting fluid yet. The plastic box they're in seems to be sealed, although I know it can't be. Man, now I can't figure out how get to the fuel pump/ac relays.
