I was doing a tune up on my 90 4.9 and was astonished at what I found.1 plug was a MC, another was a Champion, and 4 were Autolites. One plug had less than .010 gap! Also a mix matched set of wires! The P.O of this thing I guess didn't care to much about the up keep of this thing at all. Needless to say, it runs very smooth now with power to boot. The only thing I haven't replaced yet is the fuel filter. I plan to do it today after work. I'm hoping it will solve my hard starting issue. It takes about two or three tries and I have to pump the throttle a little while it stumbles to get her going. Only other thing I can think of at the moment is timing. Which I will also check this afternoon. Any suggestions other than this would be welcome.

 

Question about a tune up!
Mine takes about 5-8 sec to start, should I do a tune up?
How do you do the timing on these trucks?

PS-bikertrash, I understand that! When I first bought my truck there was so many differnet parts that didn't belong I almost flipped! Got to hate lazy owners!

 

Goes to show you how people are... bet he replaced bad plugs only...

 

Oh my lanta, that's terrible.
My truck may not be the best looking, but the original owner always replaced everything with top quality parts. A lot of stuff was done professionally too.

 

To check timing on these trucks you'll have to locate the SPOUT, SPark OUT connector. First warm your engine to operating temperature, pull the connector, and shine your timing light on the crank pulley and it should be at 10* BTDC. If not, loosen the distributor and adjust accordingly. If your timing is correct and you still have problems refer back to losthillbilly's thread about "bucking." I think I've posted some usefull info there. As to weather or not to do a tune up, it depends on how long its been since the last one. If you can't remember or don't know, ya might as well. Be cautious though I just spent about $150+ on what I've done so far.

 

IMO if one is bad then all are bad. I mean how cheap can you be. I just paid $2.29 a piece for motorcraft coppers! That's less than $15 after tax!

 

Come on dude, he had to buy his Skoal first

 

I chew Copenhagen! Bad excuse! But really though, I'm raising three kids, 7,6,5, and married making a meager 25-28k per year as the sole income. I can afford 6 good spark plugs!

 

I don't know how you do it bikertrash. God bless you.
Anyway, I'm in college work on a farm make less than 200 bucks a week pay 30+k a year for college let alone books n **** and I could afford the same plugs as you, previous owner is a bum.
And I chew copenhagen too! hahaha

 

I knew there was something I liked about you.

 

I thought it was the love for the bricknose, guess it came down the the stuff that really matters.

 

Hey guys, do me a favor and get a room before I barf

 

Well get ready truckguy!!! Russo I can get along with anyone who can appreciate a bricknose and see it as an acceptable truck to any other. But the snuff thing is just that much better. I own some stock in U.S. Smokeless. So its all good! Suggestion don't buy any!

 

Look up my brother Fordguy24... take a gander at his 90 250... it's mint, bought/custom order new buy our dad
