Is it OK to ask about similar problem to avoid creating new threads? If yes, here's my problem:
First of all - I am based in Poland, where there are no dealers ready to help with such an exotic car - literally there are more lambos and ferraris on the streets in Europe than retro-birds. I have (I woulb be very glad to say - I drive, but no, I don't) 2003 clean title 42K miles Ford Thunderbird. When I bought it, it was working fine - but after a couple of hundreds km it stalled and I wouldn't start up. During the time I was waiting for tow truck I tried multiple times to start - it cranks, but wouldn't start.
Since then - It starts sometimes and I can drive it as long as it works. It;s enough to turn off the engine to not be able to start it up again. Sometimes for an hour, sometimes for a week.
What has been done and checked until now:
new fuel pump, new filter, new evap valve, new
gas cap, new
coils, new
spark plugs, new battery, new crankshaft position sensor. CHecked every ground points I could find. Checked fuel pressure and it's perfect. But there is no regularity and rule - After a month it starts from the first rev, than from the second or third, and after four or five ignitions it just cranks. Btw - every time it cranks a little longer before it starts. And than it cranks and cranks and cranks. And after a couple of days it starts, but just once and works till I turn it off and that's it.
Forscan shows some codes - but related to taillights (needed to be rewired to comply with european standards like amber turn signals - however it cannot be the cause, because it simetimes starts, and codes for rear lights are permanent).
I have three keys - two regular ones and one without transponder - the one without transponder is not recognized by the security system - it dosn't start
fuel pump and starter, so I know that two remaining keys are fine - red light on dashboard reacts to them in a proper manner, as described in manual.
What else should I check? Any ideas?
