My first run at the 1/4 for the day and here is what happened. I think my clutch slipped so when i shifted to 3rd I bounced off the rev limiter. Cars dies mid track, lights were on the dash I turn it over while rolling and it starts roughly. Continue to get my timeslip my car dies when i stop. rough to start but get it back moving until ultimately it dies and wont start. I tow it home.

It trys to turn over but weirdly the rpms barely budge from "0",

SPARK: Checked, got a good spark from each plug wire
ENGINE CODES: 1 for 02 sensor (recent dp install)
FLOODED? Used the unflooding procedure, atf, with a jump in case my battery was dead..nothing
MAP: fully attached
FUSES: all fine from what i can tell
FUEL: pump working, jumped f/p to ground and removed fuel line near oil filler neck and have fuel pressure
Coolant looks good, oil level fine
I can hear even compression pulses, feel the pulses coming out the holes. I was unsuccessful trying to read compression I couldn't get any reading. I know blown motors start...the main pulley moves when I try to turn it over, I'm going to try to start it with starter fluid in the uim, try another compression test, and maybe a pop start ANY OTHER IDEAS?? (frustrated)

 

sounds bad... which gauge are you using to test?

here are the vids of my engine being tested... one of the vids shows no compression at all. the engine was blown, but i still managed to get her to start.

could be a coolant seal. when mine failed, it was leaking so bad that the car wouldn't start because the plugs were so wet. just a thought (although i know not a good one)

 

XStransam thanks for the great information...Looks like i have the exact gauge. Sound was similar but i didn't get no readings on either rotor..was going to attempt again but didn't get around to it today. I thought your supposed to get some compression on each?!?! Does this mean apex seal and turbo death? I fear a rebuild..

 

would it be possible to see no compression on either rotor??? I'm not seeing much of a jump in rpms. they don't really budge

 

anyone know anything about these cars where are the rotary experts on this board? help a brother out...please?

 

take the pin out of the compression tester.

 

OK, help us help you.

You need 3 things to make an ICE (internal combustion engine) run. In no particular order...

1. compression
2. fuel
3. spark

Check those 3 things and tell us what you find. The rest is just timing it all so it works right...

 

Spark, all 4 plug wires had spark

Fuel, pump works, have pressure...where do i test from here?

compression i can't get any in either rotor. Even with a jump, pedal to the floor as i'm cranking the rpms don't move from 0. So it makes sense i'm not getting compression with such a low rpm. I've read i need 200rpm minimum. Thats where i'm stumped, i hear the compression pulses....they seem even. Could it be something i'm overlooking? went from running to not in seconds..

 

mine still had sound pulses with no compression. i think its dead

 

what ecu?

 

stock ecu, Tried pop starting her to no avail....

 

when you turn the car to the on position does the check engine light come on?
