Hi,first post please be gentle with me ,im looking at buying a 1994 grand cherokee petrol with lpg conversion,the car runs fine on lpg but when switched over to petrol wont run,its the 3960 engine,even starts on lpg,would you guys stay clear of it or do you think it could be a relativly simple fix,motors priced right with good test,any advice please.

 

Bit of an update,i bought the vehicle and it really does run well on lpg,its got most of the other faults these have like the coolant sensor bad tailgate falling on my head etc etc,but quite like it.

Looked into the petrol side of it a bit and it appears to be that every time its switched over to run on petrol it blows the 20 amp fuse in the pdc,would you guys say this is most likely down to a faulty pump causing a short,theres not a lot of information on the jeep in the uk so im hoping someone over the pond can help.thanks Lyndon.
