Hi ,sorry it took a while,
Thanks very much. I used your new page to test the vehicle. I had a bulb that came in at .97 so I used that.
B5=.31
B6=.59
B8=0
B13=.09
B14=.32
B16=.17
B17=0
A8=.33
A11= NA... no pin socket
A12=0
seems all good
So as discussed my ECU was bad (no codes,no injection). I purchased an ebay rebuild and it has fixed the problem.
Some interesting notes though. The ECU would not test on the bench it threw no codes. I question my wire set up (ecu grounds light for flashes?) but... In the car it also would not register the unhooked sensors right away. It flashes 12 but no codes until it is started or turned over. Once started it registered 14,31,23 they would not self clear when rehooked up. I had to pull power to clear them. Now it runs great with an occasional code 44 that self corrects to 12 fairly quickly.
So if you remember I started with the compression check to see if the timing had slipped. I got low #'s. I gave you 50 psi cold (really Canadian -10 CELSIUS cold) but the actual #'s are;
1=40psi
2=40psi
3=50psi
4=30psi much worse....indeed.
Quote:50 is bad, on all 4 cylinder? ?????????????? no other things need checking
no injection problem i real but 50 is catastrophic bad,
the worst compression is about 150. the EFI system can NOT operate with no injection, sure test fuel works, but the EFI CANT run with no air flow. it cant.
the ECU only can compensate for normal wear, and if you thought the rings were dry ( the were not) you could put 2 squirts of oil in the cylinder and if it went from 50 to 150 then the rings
are like paper thin, useless.... end of life on rings....
if it stayed at 50psi then the valves are gone...
my guess is that not done WOT, or gauge is bad. very bad.
if all 4 are 50? the gauge is bad..
your compression gauge was dropped, and is no good, im sure, im sure it 3x greater, and is wall of shock to any tech, seeing 3x lower than normal. its Horrid.
So the car is now warmed up and the values are good, not great. They are 3 x what they were after 2 weeks of no run in down to -20 C temp. So it may be that there was less oil on the cyl. All test were done at WOT all plugs removed. The guage reads 70 psi on two 2 stroke outboards and 100 on my aircooled volkswagen. It should be good. Here are the final warm (45 min after shut down) numbers;
1= 150 psi
2= 145 psi
3= 155 psi
4= 155 psi
interesting the lowest 4 is now in the highest group....
So I would like to thank you for every thing. Your site is an incredible resource. Having access to you through the forums is amazing. I have not only fixed the tracker I have learned, and learned a lot. For that, your comments, and everything else THANKS!!!!!!!!!!!!!!!!!!!!!!
