My 2003 Buick Rendezvous would not start the other day, it acted as if the battery was dead, I jump started the car and it ran fine for 2 days and then it would not start again,everytime we would try to start the car even though the radio was turned off, it would come back oneach time wetried starting theRVD, we took the batteryand had it tested and it had tested weak but good, then we checked the altenator and appears to be good as well. Once we put everything back together it started right up, it hesitated this morning but started right up. I am afraid that I will get stranded. Anyideas would be really appreciated. Thanks

 

mass air sensor? ecu probs? try removing the ecu fuse for 5mins and replacing - if it starts first time you've just reset the ecu so it's sensing somethings up.


also try getting a carmd for $80 - looks to be a good product (no i dont work for them)
