Thread: 3.1 and no spark

i have a 1996 with a 3.1 and i have no spark i have checked the ign mod and its good. new plugs and wires havew no clue and the check codes are p1652 and p1655

crankshaft sensor or camshaft sensor

acording to alldata

p1652 is fan number 2 not workin
p1655 is evap code

my guess has to be crankshaft sensor

Thanks I will try that when I get home and what would the evap code be for

gas cap, evap line, nuthin 2 really worry bout to you get car runing

I tried the new crankhaft sensor and the camshaft sensor and still will not start

bad icm????

I have tried the crankshaft and cam sensor still no fire what else. Could it be

bad, ignition control module, or computer

I have gotten the computer flashed and I heard that there is another crankshaft sensor in the middle of the block on the back side

yes on the back of the block in between the trans and the motor

I have replaced the rear crank sensor and still no start I am getting spark now and I smell gas when I try to crank it but just won't start I have no clue I am running out of ideas please help

hold the gas down and crank the sh*t outa it mite hafta put a battery charger on it

I did try that and it did start but then it died and when it cranked there was smoke under hood coming out of the plastic tube off the rear valve cover but when it died it wouldn't start back

your prolly gona have to replace plugs, cause there fouled out cuz u were cranken it be4 with no spark, should start up now, and for the smoke thats just oil thats seeping from sittin no big deal on that

I finally got it to start but it runs ok but won't idle and I heard that the 3.1 are bad about the lower in take gasket leaking and put oil in water or vis verse I just need to know so I know what I have to do

the computers got t0 relearn,and if the oil dont look like a milkshake then there prolly ok

The reason I ask is because there is some oil residue in the radiator and was wondering if that might have someting to do with the lim gasket and the car won't idle when you let off the gas it dies and won't crank for awile

could be lim,could be seein it over heating or the radiator could just need flushed, usally there would be oil and coolant mixed in the motor lokking like a milkshake, drive it for a lil bit see if it relearns itself

I finally got it to hit but when it runs it knocks from the center of the motor and I changed the lim and the mechanic told me to torque the rockers to 18 ft pounds. But it still knocks like its the lifters please help
