Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
First we should check the battery as low voltage on start up can be the cause. Next that extended crank can be the cause if we have a failing pump. Usually that code is accompanied with others like cylinder misfire codes. If not then we may have to have the ECM reprogrammed by Jag. Let me know.
scanned the car this morning, found p050b but no low battery indications. freeze frame showed ECT 61F, IAT 59F, MAF 1.65 lb/min, STFT1 -14%, LTFT1 3.9%, STFT2 -25%, LTFT2 4.68%. Looks like too rich when cold, possible MAF problem?
Yes does sound like it is running rich. Disconnect the negative battery terminal to reset the fueling adaptions and clear the code.
