is the pump going on when you jumper the connector?? did you even check the grounds yet?

 

cloged cats maybe thats all i can think of

 

I have good pressure, so yes the pump is going on.


And yes I checked the grounds, and they all still are visually ok, and check out ok with a meter, no crazy resistance or anything.


And I have a new bonez high flow cat and dp on.

 

check if you have enough pressure at injectors and check injectors also, try swaping: fuel pump, injectors, afm, and passanger side harness, ECU... There is no way that it wouldn't run after that!

man, you have to find at least one person in your area with the same car and help each other! otherwise you will encounter too much hassle with each single problem!

 

nobody in my area has an rx7.. lol

i would swap all those parts if i had a parts car or something, im poor man.

 

If the car will still start up and idle as you said in a earlier post........then go to the tps and disconnect it. Then try driving it. Really.

A repeat of an old story....I once went to the store. I came out of the store. The car started. I went to back out of the lot.....no response from the pedal but the car would still idle. The throttle cable was on. It did not fall off. Disconnected the tps and drove home. Replaced the tps.

So...in case you do try the above, write back as to what happened and will the car still startup and idle?

 

Ill do that.. but the car will only start up and idle with the afm unplugged and the fuel pump connector jumpered.. and there is a response to the pedal, the car stalls.

 

fuel pump checks out perfect

4 new injectors (correct resistance and stuff)
afm TESTS ok, doesnt mean it is but i dont have access to another one so i guess ill just buy one from someone
ecu.. got another one and car still does same thing.

passanger side harness?

 

too cold to work on car today.. ill try the tps tomarrow if i can find time

 

new ecu, new afm, same thing.... the car will run if you hold the AFM flapper with your hand though... what does that mean?!

 

Hey dude,
I'm a total Rx N00b and havn't even got my car yet but I do know a little about the piston machines...

Have you checked simple things like the engine earth?
If the ECU isn't throwing and codes at all then it must be a earth or something the ECU can't monitor.

I don't know if your car has it but what about the coil?
Unable to rev sounds like a spark issue.

Go get a list of the things the ECU can throw codes for and then dismiss all of those things to start with and play with the things it can't monitor.

I think it's an earthing/spark issue.

If the spark is there but weak the car will idle but will be unable to rev.

Run around your car with a multimeter.

 

I have the same thing with mine, but i havent cheked the TPS. Mine starts and dies whithin two seconds. within those two seconds i can accelerate the engine up as much as i want then it dies.

 

The fuel pump operates through the Circuit Opening Relay. The Circuit Opening Relay stays energized by having a ground on it. That ground comes from the vane in the afm. When you are holding the vane open you are making that ground for the Circuit Opening Relay..........therefore the relay gets energized and the pump keeps running.
