Okay...I am still learning some of this stuff, I checked to see if the pump was working but never actually tried it while it was still hooked up in the tank. When the engine is turned over there is fuel pumping from the line...when I turn the key just to the on position I do not hear the pump prime though...and I should hear this, correct? I tried it from the line that comes from the fuel filter and from the fuel pump and got a real nice stream of gasoline pumping out when it is being turned over, but I don't get anything when the key is just turned to the on position. What am I missing here, can anybody tell me? I hope I don't sound like a complete idiot on this.

hen its just in the on position it should run for a few seconds

it only turns on the pump when the engine is turning, it doesnt run for 2 seconds when you turn the key on.

Oh, okay...I guess the next thing is to change the fuel filter, the oil and go through the de-flooding process and see if I can get it running. I guess I will have to try the pull/push starting thing with it then. Thanks for the help; I really appreciate it. I will let you know how it goes.

Quick update on the 7. I changed the oil, fuel filter, and did the procedure to de-flood it and tried to start it with no luck. I sprayed a little starting fluid into the intake and turned it over and it started but died as soon as the starting fluid ran out. I pulled off the upper rail and took out an injector and it was wet with gasoline at the top but not at the bottom. There was also what looked like rust sitting in the screened filter inside...so, I think I am going to need injectors. But I will ask this question anyway...is there any way to clean them or are they just finished? I see that they have injectors at Jegs...can I get them from them or should I try to stay with Mazda or parts from regular parts stores? I appreciate the help that you all have given me already...this is a pretty good site.



Thanks,

Ehh, I say shoot 'em with brake cleaner, but wait for a second opinion on that. I don't know anything until PROVEN knowledgeable.

Thanks for the input KA, I have a friend whose husband works in a semi-truck garage. I asked her to ask him if they clean injectors there and what it would cost to do it.

Thanks,

Well, the cleaning idea didn't come through. I checked the resistance on the injectors and got 2.7 - 3.1 on all of them. The manual says they should be 12 - 16...does that mean that these injectors are bad or that they are going bad? I do appreciate all of the help I have received so far from you guys...hopefully it will be drivable real soon.

Sounds like you may have low impedance injectors. These cars came with low imp injectors mid way thru 88 Outhers had high imp (12-14ohm). If you have a ballest resistor on the passenger side strut tower, under the air box your low imp. and 2 ohms is about right.

j9fd3s is right, a saftey feature built into these cars prevents the fule from pumping when the AFM detect's no air flow. So if you hit a teli pole and the engine dies along with you, atleast your not creamated in the car.

There is a site that gives a "how too" On checking weather or not the ecu is sending voltage to the injectors. If all else fails check the ecu.

Dose someone have the link???

theres a couple of places that clean injectors, marren, RC



also you should apply power and ground to em, and make sure they click, if they dont its bad
