Hi,I'm having issue with a 98 Toyota camry after doing a head gasket job car will not start. After pressing and depressing acceleater several time car finally starts. Codes cam and crank sensor come up. I have change cam and after replacing crank sensor car won't start either replace the old crank and I'm able to start the car with pressing and depression gas pedal. Vehicle is a 4-cylinder 2.2 mine you I did timing belt DTC is correct and still having issue with vehicles. Heads were badly warped they had to shave off .9 off the head at the Machine Shop. I have no clue where to go with this anymore I have spark I have fuel my next thing is I'm thinking about engine harness somewhere down the line it got screwed up please help I need some advice where to go from here I have read a lot of forums about this problem but noone has resolve the issue please help thank you.PS car came in running problem was overheating issue and now car wont start at the turn of the key
Was the timing set properly per the mfr recommended settings? This is a must.
Have you replaced the plugs in it? Also if you've replaced your plugs take a look at them.
In regards to the timing it can be confusing if setting the timing based off a timing belt kit as there's 2 points and one can be mistaken for the incorrect TDC.
If you bump the timing belt forward 1 tooth accidentally when installing it this can cause a issue as well.
Make sure you didn't accidentally bump any hoses or wires loose up above engine where they rest along the firewall.
Are you getting any codes with these issues when running, cranking, etc?
I agree with Dtnel. Timing is a must when doing a head gasket job and the symptoms that you are describing certainly point that way. You say you have spark and fuel, have you done a relative compression test yet just to make sure everything there is ok? After you do that and everything is fine, and your sure the timing was set up correctly, the next step I would be looking at is the Crankshaft and Camshaft sensors. Need to make sure the are working properly. Do you have a scan tool?
The other thing on this motor is the timing between the cams. If it's a 5s like I suspect there'll be scissor gears between the two cams and the cams need to be removed to access the head bolts.
Another note is to simply face a warped cylinder head is a no no on an ohc motor especially as the head is still bent and you're asking the cams to turn inside a bent head. Perhaps yours weren't too bad but that's what I've always been told.
Another thought that came to mind after reading some of the replies and combined with Scanner Danner's approach to things is have you checked the usual for proper voltages. Is this one of the early motors that had the dist that was in the head or with a coil pack? There's a lot left to check but I'm sure you'll find it quickly if you're in these forums regularly as they teach voltage like it's religion because it's the automotive religion. Let us know what comes of it as I have the 5SFE Engine myself and plan to keep it around a long long time as my 98 only has 161k miles and a lot has been replaced and it is maintained as in if it breaks I fix it except the rust but I'm fixing to look into having the vo-tech do the body work on it. Price is parts plus $5 per hour book labor so that's not to bad. It's also helping a new to industry student get hands on experience rather than changing oil in a dealer shop all the time for awhile which drives good talent away. This at least gives them experience and the confidence to show the dealership or shop mgrs that they can and are willing and able to do the job with pride.
