Own an 88 Camry Station Wagon (dx) which we purchased new. 3SFE engine. Recently (late summer 2012) went through the engine, replacing bearings, new rings, had the head worked on, etc. Replaced fuel lines, pressure regulator, pressure dampener; all new injectors - including cold start; etc. Replaced all the vacuum hoses.
Vehicle was running fine, and then it started to become difficult to start. Became more and more difficult to start - especially when cold. If you remove the intake hose, and spray ether into the throttle body - starts right up; and then runs fine. Replaced the Cold Start injector (which wasn't very old); did not solve problem.
Took the vehicle to Toyota, who spent some hours and stated the Electronic FI relay; and water temp sensor; and injection timing switch were all bad. The relay was declared to be intermittent. P/n's: (90987-02004-83; 89422-12010; & 89462-30011) Replaced all three of these; and vehicle promptly started after not being driven for over two days; and it was very cold outside. Thought it was fixed.
It does now start much more consistently - but still is exhibiting essentially same previous problem - except now when warm. (Sometimes.) And is now very intermittent problem. Starts right up; but does not necessarily start up after being shut down; and warm. We just got this 'fixed' - so it might still have problems when cold as well. To start - (if it isn't starting) you again spray in some ether - and it will start right up.
I have never replaced the Fuel Pump; and the Mass AirFlow Meter has never been replaced either. After it starts - the vehicle runs fine. And it is substantially better after replacing the three components which Toyota stated were bad. However; it previous has never had this type of problem; and I took it to Toyota because of this problem (generally do all the work myself over the years) - but it definitely still seems to have some remnants of the problem - or a very similar one.
Thanks for any help; and helpful suggestions, directions.
have the same problem?
