My HPtuner with the EIO finally came in yesterday. Today, the plan was to tune the car. I installed the program just fine. I then started the VCM Scanner and tried to start the car, and nothing. Tried a few more times and still nothing. The starter is working; the engine is turning over but just not firing. I had someone check my fpr while I cranked and the pressure was between 58-60. I then pulled out the voltmeter and verified that I am getting power at all pink wires.

(The car was running fine a couple days ago. I drove the car every other day and it drove just fine)

I checked for DTC codes and threw P0452 Fuel Tank Pressure Sensor Circuit Low Voltage. Is that code preventing the car from not starting?

IAC counts were in the 170-300 range while I cranked the engine.

Any other things I should check for?

I don't know why, but this problem is stressing me out. I can't seem to figure out what is wrong.

 

I checked #3 spark plug and it was covered with fuel and the spark plug was also black. The car must have been really rich. That must be the reason why the engine was not firing, but I will see tomorrow when i replace them.

 

Check the IGN relay as well

 

Found the problem; the plugs were fouled. Replaced them and I was able to start the car at the first try.

 

Put in some pix man!

 

LS1 in an RX7 must be damn fast. Get some pics up.

 

Still got a few things to finish up before the car is all done.

 

awesome looking car, thats gotta be sick.

 

thanx for the kind words, but i got a few things to figure out before I can really tell you how it feels.

 

Did the code go away?

 

Dang, how did you think of doing that set up?

 

The code hasn't gone away, and a whole bunch more showed up. : (
Most of the codes, though, are things i can just delete, emmissions and ac stuff.

The two that has me concerned the p0108 code, which deals with the map sensor.
Anyone know why this is coming on? It didn't before?

p0118 also came on, but I know the reason for that. The 2 wires on the little connecor that plugs into the ect sensor was cut so I tried my best to fix it, but
the connection is not kosher. I've got a wait a few days for the replacement to come in.

Another problem I encountered was that my stock thermostat wasn't opening. HPtuners scanner was registering temperature over 200 and the radiator still felt cool; I would have thought that the radiator would at least warm up.

I've also got a high idle. I'm thinking it's a vacuum leak, but anyone got any other ideas?

Too many damn problems with the car. : (
It's stressing me out.

 

oh he is not the only one take a look at www.torquecentral.com

 

THAT IS AWESOME LS1...RX7....what an amazing combo.

 

Yup, just as Sabre said, plenty of RX-7 LS1 guys around.

 

PO452 indicates high pressure in the fuel tank (low voltage= high pressure, high voltage= low pressure) which could mean a crimped evap line or fuel line. I would also check the fuel rail pressure with a gauge. Are you getting a TPS code?

 

drkphx no tps code. afaik p0452 code will not affect the way the ls1 runs in the rx7.

 

why fouled plugs?

 

i turned the car on here and there while I waited for my Hptuners to come in. The car was obviously running pig rich with the trex plus all the boltons with the stock tune.

 

Assuming your fuel pressure is ok, then that code is not bad and can be turned off.
