Need help really starting to get frustrated on this problem

[CaptainDudeMan]

Hi guys i really need some on this problem i have a 1987 Legend L 2.5L sedan i had to change all the belts fuel pump and filter and one fuel injector after replacing everything went to start the car and it just cranks and cranks so i check the main relay its ok check coil its ok and check all the fuses and check the fuel pressure all where ok so i gave it a shot of starting fluid crank it over a couple of times and then it started but real rough then the pgm-fi light came on so i check the ecu for the code and it shows code 8 tdc so now i went to pick and pull got a dizzy put it in and got the same thing i made sure to leave the battery disconnected so the ecu would reset so now its really starting to make me so i got another dizzy put that one in and still the same thing could it be possible that even though i have my cams aligned at the tdc marks could it be that i did not get the crankshaft aligned right on tdc and thats enough to trip the tdc sensor code 8 or is it just the cams that would do that or just some bad luck with the dizzys i really don't have the money for another dizzy i really need this car running so please some one give me some insight on what i could do if you like you can email me at yocaptaindudeman@gmail.com Thank you

Ok have redone the timing belt now have moved the tdc mark to the other mark on crank pulley got belt on set the tension check the marks after the 5 or 6 rotations all look good to me so now i put the dizzy i got from a junk yard in Ca i get everything in and double check all that i have done everything looks good go to start it and it just cranks and cranks WTF so i give it a shot of starting fluid after a crank or two it starts and i get that dam code 8 WTF this is the second dizzy that i have got this one was 150$ but the car is running so i went and filled up the tank got home let it run for a bet turn it off now i go to start it up the next day and it cranks and cranks give it a shot of starting fluid and it fires up and then dies cant get it to start at all even with the starting fluid so i check the main relay its ok so now i have no clue what to do so if anyone have any suggestions at all please do so thank you

Is the fuel feeding through the injectors? Make sure the spark plugs, wires, and distributor are working.

when you say belts.. i'm assuming you changed out the Timing Belt too right? when i switched out my Crank Sensor i had some issues getting it lined up correctly.. once i lined up the marks, it fired right up. there's a serious chance that you didn't install the T-belt right. i had to play with mine because even when i got the marks dead on the issue came with the slack of the belt in between the right bank *the forward cam* and the crank gear... i was leaving too much slack on it, so when it went together the crank was turning prior to the cams and so it was off a bit. then i played with it and finally got it to go together right by turning the forward cam a little clockwise so that when i put the belt on *and let the cam go* it would already have the right slack on it.. then again, i have to ask if you put the crank's timing mark at BTDC or the white TDC markings?


also, have you check the continuity of the connector going to the dizzy? and since you replaced it... are you dead certain that you put the spiral gear in the same exact position?... you could always manually spin the dizzy cap and try starting it in different positions... to check and see if you just possibly put the dizzy in a gear or two off. i was gonna say that that isn't likely cause of the initial problem before you replaced it, but there always a chance of it being two issues at once * the bad distributor at first, and now the incorrect positioning*

but if messing with the distributor isn't helping, you really need to check on the T-belt's positioning. there is some room for error, a tooth or two over and you shouldn't bend vavles, but too much you can. so be careful of your compression numbers.

yeah, and what J said.. gotta check for fuel and spark through all the components..

l4zy415 thanks for replying to my post far as i can tell the fuel is good to go and as the spark plug wires go i check each one for resistance all of them check out ok and i check the dizzy for spark and its putting out a nice spark

dblanehopr thanks for replying to my post when i did the timing belt the markers on the crankshaft are a little confusing to me the ones i can see are 3 marks in a bunch and then 2 more up from those marks but my pulley is quite bang up and none of the marks have any color on them that i can see so i made sure the the crankshaft key was exactly vertical or maybe what look vertical to me at the time when i did it i also made sure that the timing belt got good tension on it now you said the issue came with the slack of the belt in between the right bank *the forward cam* and the crank gear.when i got it on and did the tension i made sure to rotate the crankshaft 6 full rotations and then check my marks from what i can see is my cams are right on but when i look down at timing pointer it looks like one of the marks are off on the crankshaft so i think i got to go through the hole process again or what do you think

So is it like this when you had it on the TDC:

^^^ it sure sounds like the culprit of your TDC fault... between db and l4zy, I'm sure you'll get this figured out in no time

yeah, that's sorta where i got messed up to. in the manual it tells you that there's 3 bunched up *those are the ignition timing marks* ...going with your eyes counterclockwise, the next line is the white one *the TDC mark in the above FSM page* and the next one after that is a blue line that is for double checking the tensioners operation and readjusting it.

tell you the truth, i ended up accidentally setting my T-Belt to the ignition timing marks and i ended up liking the end effect.. gave it some more umph, at least i'm pretty sure that's what happened. but for now i'd stick with gettin it lined up with the TDC mark and messing with the timing with a timing light afterwards. if the marks aren't lined up like in that diagram, it's off. *the two cam marks showing from the rubber holes, and the crank mark lined up with the front cover's needle* if only two are lined up, then it's off.

you could try turning the dizzy cap too to see if it's the distributor by itself.. when you put it back in, if it was off by a tooth, the spark contacts won't be in the correct position for ignition timing. great thing about dizzy's tho is that you can spin the cap some and see if it's just off a tooth. it'll still give a spark at the plug if it's off, it just won't be doing it at the right time. did you make marks on the dizzy when you replaced it?
