hi all i want to thank the b.b. users for information on my questions. also i want to thank lucid, A.K.A (Bruce Young) for teaching me about the lambda sond system and c.i. fuel inj. he worked with me over the last five weeks! to help me solve my problem on my 85 244ti. where the p.o. bypassed the fuel pump relay, and unhooked the fuel pump relay ground which disabeled the lambda system. this is my first k-jet volvo and i knew very little about the mechanical fuel inj.i now have the labda system components tested and running and the fuel dist adjusted, and have a decent general idea of the system. with minimul cost (80.00$ multi meter and 20.00$ 0xygen sensor) and priceless help from Bruce a very patient friend.
