i was driving my car and all of a sudden the car just stoped , no bogging or sputtering , i have spark , and fuel to the rail , but after cranking and cranking my plugs are dry . anyone have this problem before????

 

Did you check for constant battery voltage at each injector? The ECU closes the ground side of the circuit to fire each one individually.

 

should it show 12v when the car is off?

 

take the plug out of the injector and get a node light

then have someone crank the car while you look at the node to see if it turns on.

if you dont have anyone jump the starter.

 

im pretty sure they arnt firing......my plugs were dry after hours of cranking.

 

pull out the injector out of the manifold and crank it to see if it sprays.

how do you know you have fuel in the rail?

 

i have a fuel pressure guage on the rail

 

what about the injector control fuse?

not sure if honda's have them (coming from subi experience), but its worth a shot.

You need to figure out WHY. If a 'noid light blinks, then you can blame the injectors. But that would be a coincidence for all to fail together. If the 'noid light doesn't blink, you still have to figure out which part of the injector circuit is farbed up.

When the ignition switch is 'ON', all the injectors are supposed to be supplied with constant battery voltage. Even if the engine isn't running. That's your first thing to check with a voltmeter. It should be the one that's the same color wire on all 4 injector plugs. Use a voltmeter to measure from that wire to ground, not to the opposite wire in the plug. I think this comes from the main relay, but I'm not sure whether the injectors have their own fuse.

When the ECU wants to fire an injector, it closes the ground side of that injector's circuit. So the injector wire that goes to the ECU is supposed to be open-circuit, except for the moment that the injector is being fired. Get it?


ps. You're getting spark, right? I think that was from your IM conversation with me, or maybe from your other thread... Anyway, if you're consistantly getting spark, you can assume your ignition switch is OK. If you sometimes get spark & sometimes don't, that's different...

 

thanks alot jim , i need to go buy a noid , the way the car died i would bet my pink that the injectors are still good , i really would. i gotta try and figure out why they arnt getting power.

 

oh where can i get a noid anywaY?

I don't have one. Even without one, you can start out by checking for battery voltage at the injector plugs. It only takes about a minute to check that...

If you don't have a multi-meter, that's probably a more important tool to buy first.
No wait, it's DEFINITELY more important.

 

hehehe ya i got a fluke somewhere ill have to find it.

ill test it , but when i find out theres no power ill have to go from there..... so if there is power , and what not , that means that it could be somthing like my crank angle sensor ?

 

No, if your crank angle sensor was shot, I think you wouldn't have spark either. The ECU apparently knows that the engine is spinning.

If there's no battery voltage at each injector, then you go 'upstream' in that circuit until you find what's broke. You've got what, a 2000 engine with a turbo? I don't have a wiring diagram for that...

If there IS battery voltage there, then you can check continuity back to the ECU on the other wire in each injector plug. Maybe that's broken. But again, it would have to be a coincidence for the 4 wires to break at once.

Piece by piece, systematically, get it? That way you know what's checked. Don't get too far ahead of yourself. I don't want to send you 14 steps down the road & then find out you never actually checked the earlier stuff.

 

ya ill start looking tomorowwhen i get back to my car.
