740GLE Engine B230F 1990 Starting problem
During past months I got starting problems from time to time (impossible to re-start after running or engine stopped without reason). Recently it really would no more start.
1/Maintenance manual of this car indicate engine B230F with LH Jetronic 2.2.
Litterature I found say LH jetronic 2.2 for B230FT (turbo) and 2.4 for B230F.Do you know if B230F has been equipped with Jetronic 2.2 and where it is possible to get diagram and diagnostic procedure?
2/Fuel injection relay (item 135)was sometimes not working properly. Change for a new one.Now when I switch on I could hear the 2 pumps running for 1-2 seconds (hearing tank pump by using a flexible hose introduce in the tank).
3/If I disconnect the fuel pressure regulator from the distribution pipe the fuel is flowing when I switch on. The fuel fiter is new (3000 miles)
4/If I spray start pilot at the engine inlet the engine start without problem and run as long as I spray. So I conclude Ignition side and ignition module are OK
5/Using diagnostic unit (cable into socket 6)
Press 1 time= 1.1.1 Injection system OK. 2 times 3.3.4 TPS OK 1.4.1 RPM sensor OK
6/Radio suppression relay OK
7/I read that 740/760 are equipped with LUXOR injection amplifier (traction control). Where is fitted this amplifier? Some doc about it?
Conclusion: I am a poor Frenchy not readdy to pay a fortune to VOLVO.If you understand my bad english and if you some idea many thanks for your answer.
