Fiat Panda 1000ie Marelli SPI (single point injector) < 50000 miles, all mint!
Hi
I’m stuck now, so any help gratefully appreciated.
My Panda was not firing on cylinder No. 1 (nearest cam belt).
* I took the plug lead off, and no difference in running, and the HT lead would spark when I touched the cam cover.
* I removed the spark plug from that cylinder, and it was very black. Put the plug into the HT lead and held that on the cam cover - I could see the spark. Messed about swapping lead about, and the 2 coil packs, issue remained on No.1
* Checked the compression with my ancient compression tester, and No. 1was 11 bar, all the others were about 11.5 (engine cold, fuses taken out of fuel pump).
* No gunge in the oil or water, but just in case I took the head off. No. 1 piston showed signs of “just started to have been cleaned”, so it’s either down to steam from a head gasket fail, or the petrol not burning and cleaning it up. All the other pistons were black on top, so these were all cleaned up.
* Old head gasket looked fine, no sign of trouble.
* Cam shaft rotated, and all 8 valves open and close.
* Exhaust and inlet manifolds taken off.
* All cleaned up, blast with the air line for final clean.
* New head bolts and head gasket gasket fitted, along with intake and exhaust manifold gaskets.
* All put back with new cam belt kit, spark plugs
* it still doesnt fire on No.1 cylinder. Grrrrr
* Back to basics! tried swapping HT leads and coil pack - and the fault stays on No.1.
* Even tried swapping the ECU with our other Panda, no change.
* I’m stuck now, no other ideas, so over to you all in Pandaland???
* I’m at LS249RA
