302 does not run on gas. Code 126
Hi there,
I'm back with an old problem, my 302 does still not run on gas but is OK on propane.
As recommended at several occasion on this forum, I have now obtained a code reader (OBD I) which was brought by friends on vacation in the USA.
I have run the tests and with KOEO I am only getting a code 126, which meansMAP sensor out of selftest range.
Then I get a code 10 (separator) then a 111, which means no contineous codes in memeory.
Ofcourse, I cannot run the KOEO as the engine does not run on gas.
A code 126 should not prevent the engine from running.
What do I do with this code?
On Fuelinjection.com it is described that the MAP sensor does not have a voltage as output, but a frequency, varying from 80 to 159 Hz, but how in the world does one measure this without a 'scoop?
I've been to the Ford dealer, responsible for service and warranty for USA products, but they can not find the problem either, despite 3 call to the Tech Dept. in the USA (Tech helpdesk). If they can not find it, what should I do?
The previous history and all the checks are listed here:

Any comments are wellcome.
Thanks for the effort.

I don't see how that could keep it from running either. I would have a talk with the installers. I assume it ran when it was first converted. How long did it go before it stopped running on gas?
I wish I knew more (well, anything, really) about LPG conversions, especially on EFI vehicles. I'll do some research.
