Ugh...cranking but no starting

[SpecM]

But if the TB boot is not there, then the MAF will not read air flow!

and the m42 uses an AFM... so...

My comment about compression was in responce to your video clips... the engine cranking is not steady, it has slow and fast spots. The engine "sounds" like it has uneven compression. However, listing to cranking (exp over the internet haha) to deteramne compression is subjective and sometimes inaccurate; so take that comment with a grain of salt!

is it possible that since the rings haven't really been seated yet that i may be experiencing the loss in compression?

possably, but not enough for it not to start

haha dude the entire engine harness from the m42 is long gone!

the tb boot was on the throttle body along with the maf...so yeh it was most certainly hooked up.

in that video everything is hooked up :)

man it fucking sucks that the car is so far away. i swear if it doesn't start this weekend its getting towed back to my place.

oh, ok. I miss-understood your other posts. sorry!

hope you get it worked out, let us know about the spark

i forgot to mention that i did have the MAF hooked up. it did however come from a 318i...4 prong.
.....?

so, you're using an obd2 m44 hfm? im assuming 413 obd1 dme? sorry, im jsut a bit confused.

its all good dude...anything helps really.

i should probably mention that the coil does give spark because i took it out and shoved a screw driver in there. there is most certainly current travelling through the coil i'm just not sure the spark plug is actually getting it.

so, you're using an m44 hfm?

yes, yes i am...it must be wrong. the ecu is a silver label 413 with EWS delete :)

does anyone have a correct p/n for the maf?

i found:

let me know if the link doesn't work..

..

hfm for obd1 e36 m50 b25 or b30
01 HOT-FILM AIR MASS METER 4-POL 1 13621747155 $438.59
should be able to pick one up (3" oem) off ebay or bimmerforums for really cheap.
or the 3.5" euro / 540, but they you will want a new chip / injectors. cheers, jason

i am actually thinking about getting the 540i maf but will get chip and injectors shortly.

do you think it will run okay with the bigger maf?

the p/n applies for b25 and b30, i checked realoem last night..

[dude8383]

added engine info, maybe this can help

[dude8383]

just a thought...but could the "uneven" compression sound like its trying to turn over?

thats pretty much why it didn't sound unusual to me...

ugh i can't wait to go take a look at the CPS and spark.

[dude8383]

Started it today!!!!!

That dash of oil helped fire this thing up like nobody's business.

I'll have the video up shortly! It sounds pretty good to me, but I can barely tell cause this thing is so flippin loud.

It won't idle though so I need to look into why...me thinks it is the M44 318i MAF

[SpecM]

where did you add the oil?

[dude8383]

Pour a dash of motor oil into cyliders via spark plug holes.

where did you add the oil?

I hope to head out to L.I. tomorrow and resolve the idle issue along with possibly mounting exhaust!

Damn its loud...but very hairy chested.

[318isbmw]

Glad its starting for you. Yeah I'd think that the hfm would be the reason for it not idling right.

[e30s52]

try ebay ss headers that is loud as hell. nice job starting it. go get your self a m50 obd1 maf and it will idle. welcome to the club
