Hi,
I am a newby to Range Rovers and have taken on a project to build a light weight tube frame rear engine buggy using P38 mechanicals.
Been helping a mate race a RR classic based Bowler and quite liked the rear engine buggies racing in the comp safari's.
Donor car is a 1995 P38A with Gemms that was refitted with a Coscast engine about 60K Miles ago. Assured it is a good engine but need to see it running and check it does not loose coolant before I tear it down and simplify electronics (to engine + trans management only). It has not been running for about 4 years. Brother has 99 p38b with Bosch management (and in need of top hatting) and managed to get key code entered and alarm off with EKA technique.
Engine winds and coughs (has spark) and almost catches but won't run. Suspect fuel pump is not running while cranking.
The fuel pump does it's 3 sec approx bit (Fuel flows at entry to injection rail) when key is turn to position II and then stops as I have seen is normal. I expect it then continues to pressurise the rail when cranking but suspect it is not doing this. Checked relay, fuse and inertial switch - all appear ok. Could it be crank position sensor or check valve or pressure regulator. I will buy a fuel pressure gauge. Not sure if my OBDII analyser I use for the corvette (C6) will work on the LR.
I have downloaded the P38 RAVE manual and electrical trouble shooting guide in pdf but it is difficult to navigate (just one big document). It assumes more accurate location of the fault as a starting point which is difficult without fault codes. It does have an injection fault warning on the dash panel when cranking. Check engine light does come on so not likely to be synchronization fault which appears to be common. Unlikely it would fire at all if that were the case.
I have looked on this and other forums but not seen (or been able to find) anything similar.
Any help appreciated.
